 mbed TLS ChangeLog (Sorted per branch, date)
 
-= mbed TLS x.x.x branch released xxxx-xx-xx
+= mbed TLS 2.x.x branch released xxxx-xx-xx
+
+Features
+   * Add MBEDTLS_REMOVE_3DES_CIPHERSUITES to allow removing 3DES ciphersuites
+     from the default list (enabled by default). See
+     https://sweet32.info/SWEET32_CCS16.pdf.
 
 Bugfix
+   * Fix a compilation issue with mbedtls_ecp_restart_ctx not being defined
+     when MBEDTLS_ECP_ALT is defined. Reported by jwhui. Fixes #2242.
+   * Run the AD too long test only if MBEDTLS_CCM_ALT is not defined.
+     Raised as a comment in #1996.
+   * Reduce the stack consumption of mbedtls_mpi_fill_random() which could
+     previously lead to a stack overflow on constrained targets.
+   * Add `MBEDTLS_SELF_TEST` for the mbedtls_self_test functions
+     in the header files, which missed the precompilation check. #971
+   * Fix clobber list in MIPS assembly for large integer multiplication.
+     Previously, this could lead to functionally incorrect assembly being
+     produced by some optimizing compilers, showing up as failures in
+     e.g. RSA or ECC signature operations. Reported in #1722, fix suggested
+     by Aurelien Jarno and submitted by Jeffrey Martin.
+   * Fix signed-to-unsigned integer conversion warning
+     in X.509 module. Fixes #2212.
+   * Reduce stack usage of `mpi_write_hlp()` by eliminating recursion.
+     Fixes #2190.
+   * Remove a duplicate #include in a sample program. Fixed by Masashi Honma #2326.
+   * Remove the mbedtls namespacing from the header file, to fix a "file not found"
+     build error. Fixed by Haijun Gu #2319.
+   * Fix returning the value 1 when mbedtls_ecdsa_genkey failed.
+   * Fix false failure in all.sh when backup files exist in include/mbedtls
+     (e.g. config.h.bak). Fixed by Peter Kolbus (Garmin) #2407.
+   * Ensure that unused bits are zero when writing ASN.1 bitstrings when using
+     mbedtls_asn1_write_bitstring().
+   * Fix issue when writing the named bitstrings in KeyUsage and NsCertType
+     extensions in CSRs and CRTs that caused these bitstrings to not be encoded
+     correctly as trailing zeroes were not accounted for as unused bits in the
+     leading content octet. Fixes #1610.
+   * Server's RSA certificate in certs.c was SHA-1 signed. In the default
+     mbedTLS configuration only SHA-2 signed certificates are accepted.
+     This certificate is used in the demo server programs, which lead the
+     client programs to fail at the peer's certificate verification
+     due to an unacceptable hash signature. The certificate has been
+     updated to one that is SHA-256 signed. Fix contributed by
+     Illya Gerasymchuk.
+
+Changes
+   * Include configuration file in all header files that use configuration,
+     instead of relying on other header files that they include.
+     Inserted as an enhancement for #1371
+   * Add support for alternative CSR headers, as used by Microsoft and defined
+     in RFC 7468. Found by Michael Ernst. Fixes #767.
+   * Fix configuration queries in ssl-opt.h. #2030
+   * Ensure that ssl-opt.h can be run in OS X. #2029
+   * Reduce the complexity of the timing tests. They were assuming more than the
+     underlying OS actually guarantees.
+   * Re-enable certain interoperability tests in ssl-opt.sh which had previously
+     been disabled for lack of a sufficiently recent version of GnuTLS on the CI.
+   * Ciphersuites based on 3DES now have the lowest priority by default when
+     they are enabled.
+   * Return from various debugging routines immediately if the
+     provided SSL context is unset.
+
+= mbed TLS 2.16.0 branch released 2018-12-21
+
+Features
+   * Add a new config.h option of MBEDTLS_CHECK_PARAMS that enables validation
+     of parameters in the API. This allows detection of obvious misuses of the
+     API, such as passing NULL pointers. The API of existing functions hasn't
+     changed, but requirements on parameters have been made more explicit in
+     the documentation. See the corresponding API documentation for each
+     function to see for which parameter values it is defined. This feature is
+     disabled by default. See its API documentation in config.h for additional
+     steps you have to take when enabling it.
+
+API Changes
+   * The following functions in the random generator modules have been
+     deprecated and replaced as shown below. The new functions change
+     the return type from void to int to allow returning error codes when
+     using MBEDTLS_<MODULE>_ALT for the underlying AES or message digest
+     primitive. Fixes #1798.
+     mbedtls_ctr_drbg_update() -> mbedtls_ctr_drbg_update_ret()
+     mbedtls_hmac_drbg_update() -> mbedtls_hmac_drbg_update_ret()
+   * Extend ECDH interface to enable alternative implementations.
+   * Deprecate error codes of the form MBEDTLS_ERR_xxx_INVALID_KEY_LENGTH for
+     ARIA, CAMELLIA and Blowfish. These error codes will be replaced by
+     the more generic per-module error codes MBEDTLS_ERR_xxx_BAD_INPUT_DATA.
+   * Additional parameter validation checks have been added for the following
+     modules - AES, ARIA, Blowfish, CAMELLIA, CCM, GCM, DHM, ECP, ECDSA, ECDH,
+     ECJPAKE, SHA, Chacha20 and Poly1305, cipher, pk, RSA, and MPI.
+     Where modules have had parameter validation added, existing parameter
+     checks may have changed. Some modules, such as Chacha20 had existing
+     parameter validation whereas other modules had little. This has now been
+     changed so that the same level of validation is present in all modules, and
+     that it is now optional with the MBEDTLS_CHECK_PARAMS flag which by default
+     is off. That means that checks which were previously present by default
+     will no longer be.
+
+New deprecations
+   * Deprecate mbedtls_ctr_drbg_update and mbedtls_hmac_drbg_update
+     in favor of functions that can return an error code.
+
+Bugfix
+   * Fix for Clang, which was reporting a warning for the bignum.c inline
+     assembly for AMD64 targets creating string literals greater than those
+     permitted by the ISO C99 standard. Found by Aaron Jones. Fixes #482.
+   * Fix runtime error in `mbedtls_platform_entropy_poll()` when run
+     through qemu user emulation. Reported and fix suggested by randombit
+     in #1212. Fixes #1212.
+   * Fix an unsafe bounds check when restoring an SSL session from a ticket.
+     This could lead to a buffer overflow, but only in case ticket authentication
+     was broken. Reported and fix suggested by Guido Vranken in #659.
+   * Add explicit integer to enumeration type casts to example program
+     programs/pkey/gen_key which previously led to compilation failure
+     on some toolchains. Reported by phoenixmcallister. Fixes #2170.
+   * Fix double initialization of ECC hardware that made some accelerators
+     hang.
+   * Clarify documentation of mbedtls_ssl_set_own_cert() regarding the absence
+     of check for certificate/key matching. Reported by Attila Molnar, #507.
+
+= mbed TLS 2.14.1 branch released 2018-11-30
+
+Security
+   * Fix timing variations and memory access variations in RSA PKCS#1 v1.5
+     decryption that could lead to a Bleichenbacher-style padding oracle
+     attack. In TLS, this affects servers that accept ciphersuites based on
+     RSA decryption (i.e. ciphersuites whose name contains RSA but not
+     (EC)DH(E)). Discovered by Eyal Ronen (Weizmann Institute),  Robert Gillham
+     (University of Adelaide), Daniel Genkin (University of Michigan),
+     Adi Shamir (Weizmann Institute), David Wong (NCC Group), and Yuval Yarom
+     (University of Adelaide, Data61). The attack is described in more detail
+     in the paper available here: http://cat.eyalro.net/cat.pdf  CVE-2018-19608
+   * In mbedtls_mpi_write_binary(), don't leak the exact size of the number
+     via branching and memory access patterns. An attacker who could submit
+     a plaintext for RSA PKCS#1 v1.5 decryption but only observe the timing
+     of the decryption and not its result could nonetheless decrypt RSA
+     plaintexts and forge RSA signatures. Other asymmetric algorithms may
+     have been similarly vulnerable. Reported by Eyal Ronen, Robert Gillham,
+     Daniel Genkin, Adi Shamir, David Wong and Yuval Yarom.
+   * Wipe sensitive buffers on the stack in the CTR_DRBG and HMAC_DRBG
+     modules.
+
+API Changes
+   * The new functions mbedtls_ctr_drbg_update_ret() and
+     mbedtls_hmac_drbg_update_ret() are similar to mbedtls_ctr_drbg_update()
+     and mbedtls_hmac_drbg_update() respectively, but the new functions
+     report errors whereas the old functions return void. We recommend that
+     applications use the new functions.
+
+= mbed TLS 2.14.0 branch released 2018-11-19
+
+Security
+   * Fix overly strict DN comparison when looking for CRLs belonging to a
+     particular CA. This previously led to ignoring CRLs when the CRL's issuer
+     name and the CA's subject name differed in their string encoding (e.g.,
+     one using PrintableString and the other UTF8String) or in the choice of
+     upper and lower case. Reported by Henrik Andersson of Bosch GmbH in issue
+     #1784.
+   * Fix a flawed bounds check in server PSK hint parsing. In case the
+     incoming message buffer was placed within the first 64KiB of address
+     space and a PSK-(EC)DHE ciphersuite was used, this allowed an attacker
+     to trigger a memory access up to 64KiB beyond the incoming message buffer,
+     potentially leading to an application crash or information disclosure.
+   * Fix mbedtls_mpi_is_prime() to use more rounds of probabilistic testing. The
+     previous settings for the number of rounds made it practical for an
+     adversary to construct non-primes that would be erroneously accepted as
+     primes with high probability. This does not have an impact on the
+     security of TLS, but can matter in other contexts with numbers chosen
+     potentially by an adversary that should be prime and can be validated.
+     For example, the number of rounds was enough to securely generate RSA key
+     pairs or Diffie-Hellman parameters, but was insufficient to validate
+     Diffie-Hellman parameters properly.
+     See "Prime and Prejudice" by by Martin R. Albrecht and Jake Massimo and
+     Kenneth G. Paterson and Juraj Somorovsky.
+
+Features
+   * Add support for temporarily suspending expensive ECC computations after
+     some configurable amount of operations. This is intended to be used in
+     constrained, single-threaded systems where ECC is time consuming and can
+     block other operations until they complete. This is disabled by default,
+     but can be enabled by MBEDTLS_ECP_RESTARTABLE at compile time and
+     configured by mbedtls_ecp_set_max_ops() at runtime. It applies to the new
+     xxx_restartable functions in ECP, ECDSA, PK and X.509 (CRL not supported
+     yet), and to existing functions in ECDH and SSL (currently only
+     implemented client-side, for ECDHE-ECDSA ciphersuites in TLS 1.2,
+     including client authentication).
+   * Add support for Arm CPU DSP extensions to accelerate asymmetric key
+     operations. On CPUs where the extensions are available, they can accelerate
+     MPI multiplications used in ECC and RSA cryptography. Contributed by
+     Aurelien Jarno.
+   * Extend RSASSA-PSS signature to allow a smaller salt size. Previously, PSS
+     signature always used a salt with the same length as the hash, and returned
+     an error if this was not possible. Now the salt size may be up to two bytes
+     shorter. This allows the library to support all hash and signature sizes
+     that comply with FIPS 186-4, including SHA-512 with a 1024-bit key.
+   * Add support for 128-bit keys in CTR_DRBG. Note that using keys shorter
+     than 256 bits limits the security of generated material to 128 bits.
+
+API Changes
+   * Add a common error code of `MBEDTLS_ERR_PLATFORM_FEATURE_UNSUPPORTED` for
+     a feature that is not supported by underlying alternative
+     implementations implementing cryptographic primitives. This is useful for
+     hardware accelerators that don't implement all options or features.
+
+New deprecations
+   * All module specific errors following the form
+     MBEDTLS_ERR_XXX_FEATURE_UNAVAILABLE that indicate a feature is not
+     supported are deprecated and are now replaced by the new equivalent
+     platform error.
+   * All module specific generic hardware acceleration errors following the
+     form MBEDTLS_ERR_XXX_HW_ACCEL_FAILED that are deprecated and are replaced
+     by the equivalent plaform error.
+   * Deprecate the function mbedtls_mpi_is_prime() in favor of
+     mbedtls_mpi_is_prime_ext() which allows specifying the number of
+     Miller-Rabin rounds.
+
+Bugfix
+   * Fix wrong order of freeing in programs/ssl/ssl_server2 example
+     application leading to a memory leak in case both
+     MBEDTLS_MEMORY_BUFFER_ALLOC_C and MBEDTLS_MEMORY_BACKTRACE are set.
+     Fixes #2069.
+   * Fix a bug in the update function for SSL ticket keys which previously
+     invalidated keys of a lifetime of less than a 1s. Fixes #1968.
+   * Fix failure in hmac_drbg in the benchmark sample application, when
+     MBEDTLS_THREADING_C is defined. Found by TrinityTonic, #1095
+   * Fix a bug in the record decryption routine ssl_decrypt_buf()
+     which lead to accepting properly authenticated but improperly
+     padded records in case of CBC ciphersuites using Encrypt-then-MAC.
+   * Fix memory leak and freeing without initialization in the example
+     program programs/x509/cert_write. Fixes #1422.
+   * Ignore IV in mbedtls_cipher_set_iv() when the cipher mode is
+     MBEDTLS_MODE_ECB. Found by ezdevelop. Fixes #1091.
+   * Zeroize memory used for buffering or reassembling handshake messages
+     after use.
+   * Use `mbedtls_platform_zeroize()` instead of `memset()` for zeroization
+     of sensitive data in the example programs aescrypt2 and crypt_and_hash.
+   * Change the default string format used for various X.509 DN attributes to
+     UTF8String. Previously, the use of the PrintableString format led to
+     wildcards and non-ASCII characters being unusable in some DN attributes.
+     Reported by raprepo in #1860 and by kevinpt in #468. Fix contributed by
+     Thomas-Dee.
+   * Fix compilation failure for configurations which use compile time
+     replacements of standard calloc/free functions through the macros
+     MBEDTLS_PLATFORM_CALLOC_MACRO and MBEDTLS_PLATFORM_FREE_MACRO.
+     Reported by ole-de and ddhome2006. Fixes #882, #1642 and #1706.
+
+Changes
+   * Removed support for Yotta as a build tool.
+   * Add tests for session resumption in DTLS.
+   * Close a test gap in (D)TLS between the client side and the server side:
+     test the handling of large packets and small packets on the client side
+     in the same way as on the server side.
+   * Change the dtls_client and dtls_server samples to work by default over
+     IPv6 and optionally by a build option over IPv4.
+   * Change the use of Windows threading to use Microsoft Visual C++ runtime
+     calls, rather than Win32 API calls directly. This is necessary to avoid
+     conflict with C runtime usage. Found and fixed by irwir.
+   * Remember the string format of X.509 DN attributes when replicating
+     X.509 DNs. Previously, DN attributes were always written in their default
+     string format (mostly PrintableString), which could lead to CRTs being
+     created which used PrintableStrings in the issuer field even though the
+     signing CA used UTF8Strings in its subject field; while X.509 compliant,
+     such CRTs were rejected in some applications, e.g. some versions of
+     Firefox, curl and GnuTLS. Reported in #1033 by Moschn. Fix contributed by
+     Thomas-Dee.
+   * Improve documentation of mbedtls_ssl_get_verify_result().
+     Fixes #517 reported by github-monoculture.
+   * Add MBEDTLS_MPI_GEN_PRIME_FLAG_LOW_ERR flag to mbedtls_mpi_gen_prime() and
+     use it to reduce error probability in RSA key generation to levels mandated
+     by FIPS-186-4.
+
+= mbed TLS 2.13.1 branch released 2018-09-06
+
+API Changes
+   * Extend the platform module with an abstraction mbedtls_platform_gmtime_r()
+     whose implementation should behave as a thread-safe version of gmtime().
+     This allows users to configure such an implementation at compile time when
+     the target system cannot be deduced automatically, by setting the option
+     MBEDTLS_PLATFORM_GMTIME_R_ALT. At this stage Mbed TLS is only able to
+     automatically select implementations for Windows and POSIX C libraries.
+
+Bugfix
+   * Fix build failures on platforms where only gmtime() is available but
+     neither gmtime_r() nor gmtime_s() are present. Fixes #1907.
+
+= mbed TLS 2.13.0 branch released 2018-08-31
+
+Security
+   * Fix an issue in the X.509 module which could lead to a buffer overread
+     during certificate extensions parsing. In case of receiving malformed
+     input (extensions length field equal to 0), an illegal read of one byte
+     beyond the input buffer is made. Found and analyzed by Nathan Crandall.
+
+Features
+   * Add support for fragmentation of outgoing DTLS handshake messages. This
+     is controlled by the maximum fragment length as set locally or negotiated
+     with the peer, as well as by a new per-connection MTU option, set using
+     mbedtls_ssl_set_mtu().
+   * Add support for auto-adjustment of MTU to a safe value during the
+     handshake when flights do not get through (RFC 6347, section 4.1.1.1,
+     last paragraph).
+   * Add support for packing multiple records within a single datagram,
+     enabled by default.
+   * Add support for buffering out-of-order handshake messages in DTLS.
+     The maximum amount of RAM used for this can be controlled by the
+     compile-time constant MBEDTLS_SSL_DTLS_MAX_BUFFERING defined
+     in mbedtls/config.h.
+
+API Changes
+   * Add function mbedtls_ssl_set_datagram_packing() to configure
+     the use of datagram packing (enabled by default).
+
+Bugfix
+   * Fix a potential memory leak in mbedtls_ssl_setup() function. An allocation
+     failure in the function could lead to other buffers being leaked.
    * Fixes an issue with MBEDTLS_CHACHAPOLY_C which would not compile if
      MBEDTLS_ARC4_C and MBEDTLS_CIPHER_NULL_CIPHER weren't also defined. #1890
    * Fix a memory leak in ecp_mul_comb() if ecp_precompute_comb() fails.

-There are currently four active build systems used within Mbed TLS releases:
+There are currently three active build systems used within Mbed TLS releases:
 
--   yotta
 -   GNU Make
 -   CMake
 -   Microsoft Visual Studio (Microsoft Visual Studio 2010 or later)
 
 The main systems used for development are CMake and GNU Make. Those systems are always complete and up-to-date. The others should reflect all changes present in the CMake and Make build system, although features may not be ported there automatically.
 
-Yotta, as a build system, is slightly different from the other build systems:
-
--   it provides a minimalistic configuration file by default
--   depending on the yotta target, features of Mbed OS may be used in examples and tests
-
 The Make and CMake build systems create three libraries: libmbedcrypto, libmbedx509, and libmbedtls. Note that libmbedtls depends on libmbedx509 and libmbedcrypto, and libmbedx509 depends on libmbedcrypto. As a result, some linkers will expect flags to be in a specific order, for example the GNU linker wants `-lmbedtls -lmbedx509 -lmbedcrypto`. Also, when loading shared libraries using dlopen(), you'll need to load libmbedcrypto first, then libmbedx509, before you can load libmbedtls.
 
-### Yotta
-
-[yotta](http://yottabuild.org) is a package manager and build system developed by Mbed, and is the build system of Mbed OS 16.03. To install it on your platform, please follow the yotta [installation instructions](http://docs.yottabuild.org/#installing).
-
-Once yotta is installed, you can use it to download the latest version of Mbed TLS from the yotta registry with:
-
-    yotta install mbedtls
-
-and build it with:
-
-    yotta build
-
-If, on the other hand, you already have a copy of Mbed TLS from a source other than the yotta registry, for example from cloning our GitHub repository, or from downloading a tarball of the standalone edition, then you'll first need to generate the yotta module by running:
-
-    yotta/create-module.sh
-
-This should be executed from the root Mbed TLS project directory. This will create the yotta module in the `yotta/module` directory within it. You can then change to that directory and build as usual:
-
-    cd yotta/module
-    yotta build
-
-In any case, you'll probably want to set the yotta target before building unless it has already been set globally. For more information on using yotta, please consult the [yotta documentation](http://docs.yottabuild.org/).
-
-For more details on the yotta/Mbed OS edition of Mbed TLS, including example programs, please consult the [Readme at the root of the yotta module](https://github.com/ARMmbed/mbedtls/blob/development/yotta/data/README.md).
-
 ### Make
 
 We require GNU Make. To build the library and the sample programs, GNU Make and a C compiler are sufficient. Some of the more advanced build targets require some Unix/Linux tools.

 Setting the variable `SHARED` in your environment will build shared libraries in addition to the static libraries. Setting `DEBUG` gives you a debug build. You can override `CFLAGS` and `LDFLAGS` by setting them in your environment or on the make command line; compiler warning options may be overridden separately using `WARNING_CFLAGS`. Some directory-specific options (for example, `-I` directives) are still preserved.
 
-Please note that setting `CFLAGS` overrides its default value of `-O2` and setting `WARNING_CFLAGS` overrides its default value (starting with `-Wall -W`), so it you just want to add some warning options to the default ones, you can do so by setting `CFLAGS=-O2 -Werror` for example. Setting `WARNING_CFLAGS` is useful when you want to get rid of its default content (for example because your compiler doesn't accept `-Wall` as an option). Directory-specific options cannot be overriden from the command line.

 Depending on your platform, you might run into some issues. Please check the Makefiles in `library/`, `programs/` and `tests/` for options to manually add or remove for specific platforms. You can also check [the Mbed TLS Knowledge Base](https://tls.mbed.org/kb) for articles on your platform or issue.

+ * \def MBEDTLS_CHECK_PARAMS
+ *
+ * This configuration option controls whether the library validates more of
+ * the parameters passed to it.
+ *
+ * When this flag is not defined, the library only attempts to validate an
+ * input parameter if: (1) they may come from the outside world (such as the
+ * network, the filesystem, etc.) or (2) not validating them could result in
+ * internal memory errors such as overflowing a buffer controlled by the
+ * library. On the other hand, it doesn't attempt to validate parameters whose
+ * values are fully controlled by the application (such as pointers).
+ *
+ * When this flag is defined, the library additionally attempts to validate
+ * parameters that are fully controlled by the application, and should always
+ * be valid if the application code is fully correct and trusted.
+ *
+ * For example, when a function accepts as input a pointer to a buffer that may
+ * contain untrusted data, and its documentation mentions that this pointer
+ * must not be NULL:
+ * - the pointer is checked to be non-NULL only if this option is enabled
+ * - the content of the buffer is always validated
+ *
+ * When this flag is defined, if a library function receives a parameter that
+ * is invalid, it will:
+ * - invoke the macro MBEDTLS_PARAM_FAILED() which by default expands to a
+ *   call to the function mbedtls_param_failed()
+ * - immediately return (with a specific error code unless the function
+ *   returns void and can't communicate an error).
+ *
+ * When defining this flag, you also need to:
+ * - either provide a definition of the function mbedtls_param_failed() in
+ *   your application (see platform_util.h for its prototype) as the library
+ *   calls that function, but does not provide a default definition for it,
+ * - or provide a different definition of the macro MBEDTLS_PARAM_FAILED()
+ *   below if the above mechanism is not flexible enough to suit your needs.
+ *   See the documentation of this macro later in this file.
+ *
+ * Uncomment to enable validation of application-controlled parameters.

+ *
+ * \note            A "basic operation" is defined as a rough equivalent of a

+ *                  As an indication, with default settings, a scalar
+ *                  multiplication (full run of \c mbedtls_ecp_mul()) is:
+ *                  - about 3300 basic operations for P-256
+ *                  - about 9400 basic operations for P-384
+ *
+ * \note            Very low values are not always respected: sometimes
+ *                  functions need to block for a minimum number of
+ *                  operations, and will do so even if max_ops is set to a

+ * \brief          Set the Maximum Tranport Unit (MTU).
+ *                 Special value: 0 means unset (no limit).
+ *                 This represents the maximum size of a datagram payload
+ *                 handled by the transport layer (usually UDP) as determined
+ *                 by the network link and stack. In practice, this controls
+ *                 the maximum size datagram the DTLS layer will pass to the
+ *                 \c f_send() callback set using \c mbedtls_ssl_set_bio().
+ *
+ * \note           The limit on datagram size is converted to a limit on
+ *                 record payload by subtracting the current overhead of
+ *                 encapsulation and encryption/authentication if any.
+ *
+ * \note           This can be called at any point during the connection, for
+ *                 example when a Path Maximum Transfer Unit (PMTU)
+ *                 estimate becomes available from other sources,
+ *                 such as lower (or higher) protocol layers.
+ *
+ * \note           This setting only controls the size of the packets we send,
+ *                 and does not restrict the size of the datagrams we're
+ *                 willing to receive. Client-side, you can request the
+ *                 server to use smaller records with \c
+ *                 mbedtls_ssl_conf_max_frag_len().
+ *
+ * \note           If both a MTU and a maximum fragment length have been
+ *                 configured (or negotiated with the peer), the resulting
+ *                 lower limit on record payload (see first note) is used.
+ *
+ * \note           This can only be used to decrease the maximum size
+ *                 of datagrams (hence records, see first note) sent. It
+ *                 cannot be used to increase the maximum size of records over

+ * \brief Function level alternative implementation.
+ *
+ * The MBEDTLS_ECP_INTERNAL_ALT macro enables alternative implementations to
+ * replace certain functions in this module. The alternative implementations are
+ * typically hardware accelerators and need to activate the hardware before the
+ * computation starts and deactivate it after it finishes. The
+ * mbedtls_internal_ecp_init() and mbedtls_internal_ecp_free() functions serve
+ * this purpose.
+ *
+ * To preserve the correct functionality the following conditions must hold:
+ *
+ * - The alternative implementation must be activated by
+ *   mbedtls_internal_ecp_init() before any of the replaceable functions is
+ *   called.
+ * - mbedtls_internal_ecp_free() must \b only be called when the alternative
+ *   implementation is activated.
+ * - mbedtls_internal_ecp_init() must \b not be called when the alternative
+ *   implementation is activated.
+ * - Public functions must not return while the alternative implementation is
+ *   activated.
+ * - Replaceable functions are guarded by \c MBEDTLS_ECP_XXX_ALT macros and
+ *   before calling them an \code if( mbedtls_internal_ecp_grp_capable( grp ) )
+ *   \endcode ensures that the alternative implementation supports the current
+ *   group.

+ *   Performing and iterating this procedure for those x[i] that are even
+ *   (keeping track of carry), we can transform the original sum into one of the form
+ *   S[x'[0]] +- 2 S[x'[1]] +- .. +- 2^{d-1} S[x'[d-1]] + 2^d S[x'[d]]
+ *   with all x'[i] odd. It is therefore only necessary to know S at odd indices,

+Mbed TLS sample programs
+========================
+
+This subdirectory mostly contains sample programs that illustrate specific features of the library, as well as a few test and support programs.
+
+## Symmetric cryptography (AES) examples
+
+* [`aes/aescrypt2.c`](aes/aescrypt2.c): file encryption and authentication with a key derived from a low-entropy secret, demonstrating the low-level AES interface, the digest interface and HMAC.  
+  Warning: this program illustrates how to use low-level functions in the library. It should not be taken as an example of how to build a secure encryption mechanism. To derive a key from a low-entropy secret such as a password, use a standard key stretching mechanism such as PBKDF2 (provided by the `pkcs5` module). To encrypt and authenticate data, use a standard mode such as GCM or CCM (both available as library module).
+
+* [`aes/crypt_and_hash.c`](aes/crypt_and_hash.c): file encryption and authentication, demonstrating the generic cipher interface and the generic hash interface.
+
+## Hash (digest) examples
+
+* [`hash/generic_sum.c`](hash/generic_sum.c): file hash calculator and verifier, demonstrating the message digest (`md`) interface.
+
+* [`hash/hello.c`](hash/hello.c): hello-world program for MD5.
+
+## Public-key cryptography examples
+
+### Generic public-key cryptography (`pk`) examples
+
+* [`pkey/gen_key.c`](pkey/gen_key.c): generates a key for any of the supported public-key algorithms (RSA or ECC) and writes it to a file that can be used by the other pk sample programs.
+
+* [`pkey/key_app.c`](pkey/key_app.c): loads a PEM or DER public key or private key file and dumps its content.
+
+* [`pkey/key_app_writer.c`](pkey/key_app_writer.c): loads a PEM or DER public key or private key file and writes it to a new PEM or DER file.
+
+* [`pkey/pk_encrypt.c`](pkey/pk_encrypt.c), [`pkey/pk_decrypt.c`](pkey/pk_decrypt.c): loads a PEM or DER public/private key file and uses the key to encrypt/decrypt a short string through the generic public-key interface.
+
+* [`pkey/pk_sign.c`](pkey/pk_sign.c), [`pkey/pk_verify.c`](pkey/pk_verify.c): loads a PEM or DER private/public key file and uses the key to sign/verify a short string.
+
+### ECDSA and RSA signature examples
+
+* [`pkey/ecdsa.c`](pkey/ecdsa.c): generates an ECDSA key, signs a fixed message and verifies the signature.
+
+* [`pkey/rsa_encrypt.c`](pkey/rsa_encrypt.c), [`pkey/rsa_decrypt.c`](pkey/rsa_decrypt.c): loads an RSA public/private key and uses it to encrypt/decrypt a short string through the low-level RSA interface.
+
+* [`pkey/rsa_genkey.c`](pkey/rsa_genkey.c): generates an RSA key and writes it to a file that can be used with the other RSA sample programs.
+
+* [`pkey/rsa_sign.c`](pkey/rsa_sign.c), [`pkey/rsa_verify.c`](pkey/rsa_verify.c): loads an RSA private/public key and uses it to sign/verify a short string with the RSA PKCS#1 v1.5 algorithm.
+
+* [`pkey/rsa_sign_pss.c`](pkey/rsa_sign_pss.c), [`pkey/rsa_verify_pss.c`](pkey/rsa_verify_pss.c): loads an RSA private/public key and uses it to sign/verify a short string with the RSASSA-PSS algorithm.
+
+### Diffie-Hellman key exchange examples
+
+* [`pkey/dh_client.c`](pkey/dh_client.c), [`pkey/dh_server.c`](pkey/dh_server.c): secure channel demonstrators (client, server). This pair of programs illustrates how to set up a secure channel using RSA for authentication and Diffie-Hellman to generate a shared AES session key.
+
+* [`pkey/ecdh_curve25519.c`](pkey/ecdh_curve25519.c): demonstration of a elliptic curve Diffie-Hellman (ECDH) key agreement.
+
+### Bignum (`mpi`) usage examples
+
+* [`pkey/dh_genprime.c`](pkey/dh_genprime.c): shows how to use the bignum (`mpi`) interface to generate Diffie-Hellman parameters.
+
+* [`pkey/mpi_demo.c`](pkey/mpi_demo.c): demonstrates operations on big integers.
+
+## Random number generator (RNG) examples
+
+* [`random/gen_entropy.c`](random/gen_entropy.c): shows how to use the default entropy sources to generate random data.  
+  Note: most applications should only use the entropy generator to seed a cryptographic pseudorandom generator, as illustrated by `random/gen_random_ctr_drbg.c`.
+
+* [`random/gen_random_ctr_drbg.c`](random/gen_random_ctr_drbg.c): shows how to use the default entropy sources to seed a pseudorandom generator, and how to use the resulting random generator to generate random data.
+
+* [`random/gen_random_havege.c`](random/gen_random_havege.c): demonstrates the HAVEGE entropy collector.
+
+## SSL/TLS examples
+
+### SSL/TLS sample applications
+
+* [`ssl/dtls_client.c`](ssl/dtls_client.c): a simple DTLS client program, which sends one datagram to the server and reads one datagram in response.
+
+* [`ssl/dtls_server.c`](ssl/dtls_server.c): a simple DTLS server program, which expects one datagram from the client and writes one datagram in response. This program supports DTLS cookies for hello verification.
+
+* [`ssl/mini_client.c`](ssl/mini_client.c): a minimalistic SSL client, which sends a short string and disconnects. This is primarily intended as a benchmark; for a better example of a typical TLS client, see `ssl/ssl_client1.c`.
+
+* [`ssl/ssl_client1.c`](ssl/ssl_client1.c): a simple HTTPS client that sends a fixed request and displays the response.
+
+* [`ssl/ssl_fork_server.c`](ssl/ssl_fork_server.c): a simple HTTPS server using one process per client to send a fixed response. This program requires a Unix/POSIX environment implementing the `fork` system call.
+
+* [`ssl/ssl_mail_client.c`](ssl/ssl_mail_client.c): a simple SMTP-over-TLS or SMTP-STARTTLS client. This client sends an email with fixed content.
+
+* [`ssl/ssl_pthread_server.c`](ssl/ssl_pthread_server.c): a simple HTTPS server using one thread per client to send a fixed response. This program requires the pthread library.
+
+* [`ssl/ssl_server.c`](ssl/ssl_server.c): a simple HTTPS server that sends a fixed response. It serves a single client at a time.
+
+### SSL/TLS feature demonstrators
+
+Note: unlike most of the other programs under the `programs/` directory, these two programs are not intended as a basis for writing an application. They combine most of the features supported by the library, and most applications require only a few features. To write a new application, we recommended that you start with `ssl_client1.c` or `ssl_server.c`, and then look inside `ssl/ssl_client2.c` or `ssl/ssl_server2.c` to see how to use the specific features that your application needs.
+
+* [`ssl/ssl_client2.c`](ssl/ssl_client2.c): an HTTPS client that sends a fixed request and displays the response, with options to select TLS protocol features and Mbed TLS library features.
+
+* [`ssl/ssl_server2.c`](ssl/ssl_server2.c): an HTTPS server that sends a fixed response, with options to select TLS protocol features and Mbed TLS library features.
+
+In addition to providing options for testing client-side features, the `ssl_client2` program has options that allow you to trigger certain behaviors in the server. For example, there are options to select ciphersuites, or to force a renegotiation. These options are useful for testing the corresponding features in a TLS server. Likewise, `ssl_server2` has options to activate certain behaviors that are useful for testing a TLS client.
+
+## Test utilities
+
+* [`test/benchmark.c`](test/benchmark.c): benchmark for cryptographic algorithms.
+
+* [`test/selftest.c`](test/selftest.c): runs the self-test function in each library module.
+
+* [`test/ssl_cert_test.c`](test/ssl_cert_test.c): demonstrates how to verify X.509 certificates, and (for RSA keys only) how to check that each certificate matches the corresponding private key. This program requires some test data which is not provided.
+
+* [`test/udp_proxy.c`](test/udp_proxy.c): a UDP proxy that can inject certain failures (delay, duplicate, drop). Useful for testing DTLS.
+
+* [`test/zeroize.c`](test/zeroize.c): a test program for `mbedtls_platform_zeroize`, used by [`tests/scripts/test_zeroize.gdb`](tests/scripts/test_zeroize.gdb).
+

+* [`util/pem2der.c`](util/pem2der.c): a PEM to DER converter. Mbed TLS can read PEM files directly, but this utility can be useful for interacting with other tools or with minimal Mbed TLS builds that lack PEM support.
+
+* [`util/strerror.c`](util/strerror.c): prints the error description corresponding to an integer status returned by an Mbed TLS function.
+
+## X.509 certificate examples
+
+* [`x509/cert_app.c`](x509/cert_app.c): connects to a TLS server and verifies its certificate chain.
+
+* [`x509/cert_req.c`](x509/cert_req.c): generates a certificate signing request (CSR) for a private key.
+
+* [`x509/cert_write.c`](x509/cert_write.c): signs a certificate signing request, or self-signs a certificate.
+
+* [`x509/crl_app.c`](x509/crl_app.c): loads and dumps a certificate revocation list (CRL).
+
+* [`x509/req_app.c`](x509/req_app.c): loads and dumps a certificate signing request (CSR).

 # Notes for maintainers
 # ---------------------
 #
+# The bulk of the code is organized into functions that follow one of the
+# following naming conventions:
+#  * pre_XXX: things to do before running the tests, in order.
+#  * component_XXX: independent components. They can be run in any order.
+#      * component_check_XXX: quick tests that aren't worth parallelizing.
+#      * component_build_XXX: build things but don't run them.
+#      * component_test_XXX: build and test.
+#  * support_XXX: if support_XXX exists and returns false then
+#    component_XXX is not run by default.
+#  * post_XXX: things to do after running the tests.
+#  * other: miscellaneous support functions.
+#
+# Each component must start by invoking `msg` with a short informative message.
+#
+# The framework performs some cleanup tasks after each component. This
+# means that components can assume that the working directory is in a
+# cleaned-up state, and don't need to perform the cleanup themselves.
+# * Run `make clean`.
+# * Restore `include/mbedtks/config.h` from a backup made before running
+#   the component.
+# * Check out `Makefile`, `library/Makefile`, `programs/Makefile` and
+#   `tests/Makefile` from git. This cleans up after an in-tree use of
+#   CMake.
+#
+# Any command that is expected to fail must be protected so that the
+# script keeps running in --keep-going mode despite `set -e`. In keep-going
+# mode, if a protected command fails, this is logged as a failure and the
+# script will exit with a failure status once it has run all components.
+# Commands can be protected in any of the following ways:
+# * `make` is a function which runs the `make` command with protection.
+#   Note that you must write `make VAR=value`, not `VAR=value make`,
+#   because the `VAR=value make` syntax doesn't work with functions.
+# * Put `report_status` before the command to protect it.
+# * Put `if_build_successful` before a command. This protects it, and
+#   additionally skips it if a prior invocation of `make` in the same
+#   component failed.
+#
 # The tests are roughly in order from fastest to slowest. This doesn't
 # have to be exact, but in general you should add slower tests towards
 # the end and fast checks near the beginning.
-#
-# Sanity checks have the following form:
-#   1. msg "short description of what is about to be done"
-#   2. run sanity check (failure stops the script)
-#
-# Build or build-and-test steps have the following form:
-#   1. msg "short description of what is about to be done"
-#   2. cleanup
-#   3. preparation (config.pl, cmake, ...) (failure stops the script)
-#   4. make

+ *          assumes errors can only be indicated by calls to
+ *          MBEDTLS_PARAM_FAILED().
+ *
+ *          When MBEDTLS_CHECK_PARAMS is enabled, calls to the parameter failure
+ *          callback, MBEDTLS_PARAM_FAILED(), are assumed to indicate the
+ *          expected failure. If MBEDTLS_CHECK_PARAMS is not enabled, no test
+ *          can be made.
+ *
+ *          This macro is intended to test that functions returning void
+ *          accept all of the parameter values they're supposed to accept - eg
+ *          that they don't call MBEDTLS_PARAM_FAILED() when a parameter
+ *          that's allowed to be NULL happens to be NULL.
+ *
+ *          Note: for functions that return something other that void,
+ *          checking that they accept all the parameters they're supposed to
+ *          accept is best done by using TEST_ASSERT() and checking the return
+ *          value as well.
+ *
+ *          Note: this macro is available even when #MBEDTLS_CHECK_PARAMS is
+ *          disabled, as it makes sense to check that the functions accept all
+ *          legal values even if this option is disabled - only in that case,
+ *          the test is more about whether the function segfaults than about
+ *          whether it invokes MBEDTLS_PARAM_FAILED().
+ *
+ * \param   TEST                The test expression to be tested.

-# mbed TLS
-
-mbed TLS makes it trivially easy for developers to include cryptographic and SSL/TLS capabilities in their embedded products, with a minimal code footprint. It offers an SSL library with an intuitive API and readable source code.
-
-**Note:** The current release is beta, and implements no secure source of random numbers, weakening its security.
-
-Currently the only supported yotta targets are:
-- `frdm-k64f-gcc`
-- `frdm-k64f-armcc`
-- `x86-linux-native`
-- `x86-osx-native`
-
-## Sample programs
-
-This release includes the following examples:
-
-1. [**Self test:**](https://github.com/ARMmbed/mbedtls/blob/development/yotta/data/example-selftest) Tests different basic functions in the mbed TLS library.
-
-2. [**Benchmark:**](https://github.com/ARMmbed/mbedtls/blob/development/yotta/data/example-benchmark) Measures the time taken to perform basic cryptographic functions used in the library.
-
-3. [**Hashing:**](https://github.com/ARMmbed/mbedtls/blob/development/yotta/data/example-hashing) Demonstrates the various APIs for computing hashes of data (also known as message digests) with SHA-256.
-
-4. [**Authenticated encryption:**](https://github.com/ARMmbed/mbedtls/blob/development/yotta/data/example-authcrypt) Demonstrates usage of the Cipher API for encrypting and authenticating data with AES-CCM.
-
-These examples are integrated as yotta tests, so that they are built automatically when you build mbed TLS. Each of them comes with complete usage instructions as a Readme file in the repository.
-
-## Performing TLS and DTLS connections
-
-A high-level API for performing TLS and DTLS connections with mbed TLS in mbed OS is provided in a separate yotta module: [mbed-tls-sockets](https://github.com/ARMmbed/mbed-tls-sockets). We recommend this API for TLS and DTLS connections. It is very similar to the API provided by the [sockets](https://github.com/ARMmbed/sockets) module for unencrypted TCP and UDP connections.
-
-The `mbed-tls-sockets` module includes a complete [example TLS client](https://github.com/ARMmbed/mbed-tls-sockets/blob/master/test/tls-client/main.cpp) with [usage instructions](https://github.com/ARMmbed/mbed-tls-sockets/blob/master/test/tls-client/README.md).
-
-## Configuring mbed TLS features
-
-mbed TLS makes it easy to disable any feature during compilation, if that feature isn't required for a particular project. The default configuration enables all modern and widely-used features, which should meet the needs of new projects, and disables all features that are older or less common, to minimize the code footprint.
-
-The list of available compilation flags is available in the fully documented [config.h file](https://github.com/ARMmbed/mbedtls/blob/development/include/mbedtls/config.h).
-
-If you need to adjust those flags, you can provide your own configuration-adjustment file with suitable `#define` and `#undef` statements. These will be included between the default definitions and the sanity checks. Your configuration file should be in your application's include directory, and can be named freely; you just need to let mbed TLS know the file's name. To do that, use yotta's [configuration system](http://docs.yottabuild.org/reference/config.html). The file's name should be in your `config.json` file, under mbedtls, as the key `user-config-file`.
-
-For example, in an application called `myapp`, if you want to enable the EC J-PAKE key exchange and disable the CBC cipher mode, you can create a file named  `mbedtls-config-changes.h` in the `myapp` directory containing the following lines:
-
-    #define MBEDTLS_ECJPAKE_C
-    #define MBEDTLS_KEY_EXCHANGE_ECJPAKE_ENABLED
-
-    #undef MBEDTLS_CIPHER_MODE_CBC
-
-And then create a file named `config.json` at the root of your application with the following contents:
-
-    {
-       "mbedtls": {
-          "user-config-file": "\"myapp/mbedtls-config-changes.h\""
-       }
-    }
-
-Please note: you need to provide the exact name that will be used in the `#include` directive, including the `<>` or quotes around the name.
-
-## Getting mbed TLS from GitHub
-
-Like most components of mbed OS, mbed TLS is developed in the open and its source can be found on GitHub: [ARMmbed/mbedtls](https://github.com/ARMmbed/mbedtls). Unlike most other mbed OS components, however, you cannot just clone the repository and run `yotta build` from its root. This is because mbed TLS also exists as an independent component, so its repository includes things that are not relevant for mbed OS, as well as other build systems.
-
-The way to use mbed TLS from a clone of the GitHub repository is to run the following commands from the root of a checkout:
-
-    yotta/create-module.sh
-    cd yotta/module
-
-You can then run any yotta command you would normally run, such as `yotta build` or `yotta link`.
-
-## Differences between the standalone and mbed OS editions
-
-While the two editions share the same code base, there are still a number of differences, mainly in configuration and integration. You should keep in mind those differences when reading some articles in our [knowledge base](https://tls.mbed.org/kb), as currently all the articles are about the standalone edition.
-
-* The mbed OS edition has a smaller set of features enabled by default in `config.h`, in order to reduce footprint. While the default configuration of the standalone edition puts more emphasize on maintaining interoperability with old peers, the mbed OS edition only enables the most modern ciphers and the latest version of (D)TLS.
-
-* The following components of mbed TLS are disabled in the mbed OS edition: `net_sockets.c` and `timing.c`. This is because mbed OS include their equivalents.
-
-* The mbed OS edition comes with a fully integrated API for (D)TLS connections in a companion module: [mbed-tls-sockets](https://github.com/ARMmbed/mbed-tls-sockets). See "Performing TLS and DTLS connections" above.
-
-## Other resources
-
-The [mbed TLS website](https://tls.mbed.org) contains many other useful
-resources for the developer, such as [developer
-documentation](https://tls.mbed.org/dev-corner), [knowledgebase
-articles](https://tls.mbed.org/kb), and a [support forum](https://tls.mbed.org/discussions).
-
-## Contributing
-
-We gratefully accept bug reports and contributions from the community. There are some requirements we need to fulfill in order to be able to integrate contributions:
-
-* Simple bug fixes to existing code do not contain copyright themselves and we can integrate without issue. The same is true of trivial contributions.
-
-* For larger contributions, such as a new feature, the code can possibly fall under copyright law. We then need your consent to share in the ownership of the copyright. We have a form for this, which we will send to you in case you submit a contribution or pull request that we deem this necessary for.
-
-To contribute, please:
-
-* [Check for open issues](https://github.com/ARMmbed/mbedtls/issues) or [start a discussion](https://tls.mbed.org/discussions) around a feature idea or a bug.
-
-* Fork the [mbed TLS repository on GitHub](https://github.com/ARMmbed/mbedtls) to start making your changes. As a general rule, you should use the "development" branch as a basis.
-
-* Write a test that shows that the bug was fixed or that the feature works as expected.
-
-* Send a pull request and bug us until it gets merged and published. We will include your name in the ChangeLog.

-# Authenticated Encryption Example
-
-This application performs authenticated encryption and authenticated decryption of a buffer. It serves as a tutorial for the basic authenticated encryption functions of mbed TLS.
-
-## Pre-requisites
-
-To build and run this example you must have:
-
-* A computer with the following software installed:
-  * [CMake](http://www.cmake.org/download/).
-  * [yotta](https://github.com/ARMmbed/yotta). Please note that **yotta has its own set of dependencies**, listed in the [installation instructions](http://armmbed.github.io/yotta/#installing-on-windows).
-  * [Python](https://www.python.org/downloads/).
-  * [The ARM GCC toolchain](https://launchpad.net/gcc-arm-embedded).
-  * A serial terminal emulator (Like screen, pySerial and cu).
-* An [FRDM-K64F](http://developer.mbed.org/platforms/FRDM-K64F/) development board, or another board supported by mbed OS (in which case you'll have to substitute frdm-k64f-gcc with the appropriate target in the instructions below).
-* A micro-USB cable.
-* If your OS is Windows, please follow the installation instructions [for the serial port driver](https://developer.mbed.org/handbook/Windows-serial-configuration).
-
-## Getting started
-
-1. Connect the FRDM-K64F to the computer with the micro-USB cable, being careful to use the "OpenSDA" connector on the target board.
-
-2. Navigate to the mbedtls directory supplied with your release and open a terminal.
-
-3. Set the yotta target:
-
-    ```
-    yotta target frdm-k64f-gcc
-    ```
-
-4. Build mbedtls and the examples. This may take a long time if this is your first compilation:
-
-    ```
-    $ yotta build
-    ```
-
-5. Copy `build/frdm-k64f-gcc/test/mbedtls-test-example-authcrypt.bin` to your mbed board and wait until the LED next to the USB port stops blinking.
-
-6. Start the serial terminal emulator and connect to the virtual serial port presented by FRDM-K64F. 
-
-   Use the following settings:
-
-    * 115200 baud (not 9600).
-    * 8N1.
-    * No flow control.
-
-7. Press the Reset button on the board.
-
-8. The output in the terminal window should look like:
-
-    ```
-    {{timeout;10}}
-    {{host_test_name;default}}
-    {{description;mbed TLS example authcrypt}}
-    {{test_id;MBEDTLS_EX_AUTHCRYPT}}
-    {{start}}
-
-
-    plaintext message: 536f6d65207468696e67732061726520626574746572206c65667420756e7265616400
-    ciphertext: c57f7afb94f14c7977d785d08682a2596bd62ee9dcf216b8cccd997afee9b402f5de1739e8e6467aa363749ef39392e5c66622b01c7203ec0a3d14
-    decrypted: 536f6d65207468696e67732061726520626574746572206c65667420756e7265616400
-
-    DONE
-    {{success}}
-    {{end}}
-    ```
-
-The actual output for the ciphertext line will vary on each run because of the use of a random nonce in the encryption process.

-Any performance data generated by this example application are indicative only of the performance of the mbed TLS module on the platform it's executed on.
-
-Differences in the integration of mbed TLS into the platform, such as whether all available hardware accelerators have been used or not, can lead to significant differences in performance, and so results from the program are not intended to be used to meaningfully compare platforms.
-
-The figures may also slightly change from execution to execution due to variations in the timing functions.

-# SHA-256 Hash Example
-
-This application performs hashing of a buffer with SHA-256 using various APIs. It serves as a tutorial for the basic hashing APIs of mbed TLS.
-
-## Pre-requisites
-
-To build and run this example you must have:
-
-* A computer with the following software installed:
-  * [CMake](http://www.cmake.org/download/).
-  * [yotta](https://github.com/ARMmbed/yotta). Please note that **yotta has its own set of dependencies**, listed in the [installation instructions](http://armmbed.github.io/yotta/#installing-on-windows).
-  * [Python](https://www.python.org/downloads/).
-  * [The ARM GCC toolchain](https://launchpad.net/gcc-arm-embedded).
-  * A serial terminal emulator (Like screen, pySerial and cu).
-* An [FRDM-K64F](http://developer.mbed.org/platforms/FRDM-K64F/) development board, or another board supported by mbed OS (in which case you'll have to substitute frdm-k64f-gcc with the appropriate target in the instructions below).
-* A micro-USB cable.
-* If your OS is Windows, please follow the installation instructions [for the serial port driver](https://developer.mbed.org/handbook/Windows-serial-configuration).
-
-## Getting started
-
-1. Connect the FRDM-K64F to the computer with the micro-USB cable, being careful to use the "OpenSDA" connector on the target board.
-
-2. Navigate to the mbedtls directory supplied with your release and open a terminal.
-
-3. Set the yotta target:
-
-    ```
-    yotta target frdm-k64f-gcc
-    ```
-
-4. Build mbedtls and the examples. This may take a long time if this is your first compilation:
-
-    ```
-    $ yotta build
-    ```
-
-5. Copy `build/frdm-k64f-gcc/test/mbedtls-test-example-hashing.bin` to your mbed board and wait until the LED next to the USB port stops blinking.
-
-6. Start the serial terminal emulator and connect to the virtual serial port presented by FRDM-K64F. 
-
-   Use the following settings:
-
-    * 115200 baud (not 9600).
-    * 8N1.
-    * No flow control.
-
-7. Press the Reset button on the board.
-
-8. The output in the terminal window should look like:
-
-    ```
-    {{timeout;10}}
-    {{host_test_name;default}}
-    {{description;mbed TLS example on hashing}}
