 mbed TLS ChangeLog (Sorted per branch, date)
 
+= mbed TLS 2.25.0 branch released 2020-12-11
+
+API changes
+   * The numerical values of the PSA Crypto API macros have been updated to
+     conform to version 1.0.0 of the specification.
+   * PSA_ALG_STREAM_CIPHER replaces PSA_ALG_CHACHA20 and PSA_ALG_ARC4.
+     The underlying stream cipher is determined by the key type
+     (PSA_KEY_TYPE_CHACHA20 or PSA_KEY_TYPE_ARC4).
+   * The functions mbedtls_cipher_auth_encrypt() and
+     mbedtls_cipher_auth_decrypt() no longer accept NIST_KW contexts,
+     as they have no way to check if the output buffer is large enough.
+     Please use mbedtls_cipher_auth_encrypt_ext() and
+     mbedtls_cipher_auth_decrypt_ext() instead. Credit to OSS-Fuzz and
+     Cryptofuzz. Fixes #3665.
+
+Requirement changes
+   * Update the minimum required CMake version to 2.8.12.  This silences a
+     warning on CMake 3.19.0. #3801
+
+New deprecations
+   * PSA_KEY_TYPE_CHACHA20 and PSA_KEY_TYPE_ARC4 have been deprecated.
+     Use PSA_ALG_STREAM_CIPHER instead.
+   * The functions mbedtls_cipher_auth_encrypt() and
+     mbedtls_cipher_auth_decrypt() are deprecated in favour of the new
+     functions mbedtls_cipher_auth_encrypt_ext() and
+     mbedtls_cipher_auth_decrypt_ext(). Please note that with AEAD ciphers,
+     these new functions always append the tag to the ciphertext, and include
+     the tag in the ciphertext length.
+
+Features
+   * Partial implementation of the new PSA Crypto accelerator APIs. (Symmetric
+     ciphers, asymmetric signing/verification and key generation, validate_key
+     entry point, and export_public_key interface.)
+   * Add support for ECB to the PSA cipher API.
+   * In PSA, allow using a key declared with a base key agreement algorithm
+     in combined key agreement and derivation operations, as long as the key
+     agreement algorithm in use matches the algorithm the key was declared with.
+     This is currently non-standard behaviour, but expected to make it into a
+     future revision of the PSA Crypto standard.
+   * Add MBEDTLS_TARGET_PREFIX CMake variable, which is prefixed to the mbedtls,
+     mbedcrypto, mbedx509 and apidoc CMake target names. This can be used by
+     external CMake projects that include this one to avoid CMake target name
+     clashes.  The default value of this variable is "", so default target names
+     are unchanged.
+   * Add support for DTLS-SRTP as defined in RFC 5764. Contributed by Johan
+     Pascal, improved by Ron Eldor.
+   * In the PSA API, it is no longer necessary to open persistent keys:
+     operations now accept the key identifier. The type psa_key_handle_t is now
+     identical to psa_key_id_t instead of being platform-defined. This bridges
+     the last major gap to compliance with the PSA Cryptography specification
+     version 1.0.0. Opening persistent keys is still supported for backward
+     compatibility, but will be deprecated and later removed in future
+     releases.
+   * PSA_AEAD_NONCE_LENGTH, PSA_AEAD_NONCE_MAX_SIZE, PSA_CIPHER_IV_LENGTH and
+     PSA_CIPHER_IV_MAX_SIZE macros have been added as defined in version
+     1.0.0 of the PSA Crypto API specification.
+
+Security
+   * The functions mbedtls_cipher_auth_encrypt() and
+     mbedtls_cipher_auth_decrypt() would write past the minimum documented
+     size of the output buffer when used with NIST_KW. As a result, code using
+     those functions as documented with NIST_KW could have a buffer overwrite
+     of up to 15 bytes, with consequences ranging up to arbitrary code
+     execution depending on the location of the output buffer.
+   * Limit the size of calculations performed by mbedtls_mpi_exp_mod to
+     MBEDTLS_MPI_MAX_SIZE to prevent a potential denial of service when
+     generating Diffie-Hellman key pairs. Credit to OSS-Fuzz.
+   * A failure of the random generator was ignored in mbedtls_mpi_fill_random(),
+     which is how most uses of randomization in asymmetric cryptography
+     (including key generation, intermediate value randomization and blinding)
+     are implemented. This could cause failures or the silent use of non-random
+     values. A random generator can fail if it needs reseeding and cannot not
+     obtain entropy, or due to an internal failure (which, for Mbed TLS's own
+     CTR_DRBG or HMAC_DRBG, can only happen due to a misconfiguration).
+   * Fix a compliance issue whereby we were not checking the tag on the
+     algorithm parameters (only the size) when comparing the signature in the
+     description part of the cert to the real signature. This meant that a
+     NULL algorithm parameters entry would look identical to an array of REAL
+     (size zero) to the library and thus the certificate would be considered
+     valid. However, if the parameters do not match in *any* way then the
+     certificate should be considered invalid, and indeed OpenSSL marks these
+     certs as invalid when mbedtls did not.
+     Many thanks to guidovranken who found this issue via differential fuzzing
+     and reported it in #3629.
+   * Zeroising of local buffers and variables which are used for calculations
+     in mbedtls_pkcs5_pbkdf2_hmac(), mbedtls_internal_sha*_process(),
+     mbedtls_internal_md*_process() and mbedtls_internal_ripemd160_process()
+     functions to erase sensitive data from memory. Reported by
+     Johan Malmgren and Johan Uppman Bruce from Sectra.
+
+Bugfix
+   * Fix an invalid (but nonzero) return code from mbedtls_pk_parse_subpubkey()
+     when the input has trailing garbage. Fixes #2512.
+   * Fix build failure in configurations where MBEDTLS_USE_PSA_CRYPTO is
+     enabled but ECDSA is disabled. Contributed by jdurkop. Fixes #3294.
+   * Include the psa_constant_names generated source code in the source tree
+     instead of generating it at build time. Fixes #3524.
+   * Fix rsa_prepare_blinding() to retry when the blinding value is not
+     invertible (mod N), instead of returning MBEDTLS_ERR_RSA_RNG_FAILED. This
+     addresses a regression but is rare in practice (approx. 1 in 2/sqrt(N)).
+     Found by Synopsys Coverity, fix contributed by Peter Kolbus (Garmin).
+     Fixes #3647.
+   * Use socklen_t on Android and other POSIX-compliant system
+   * Fix the build when the macro _GNU_SOURCE is defined to a non-empty value.
+     Fix #3432.
+   * Consistently return PSA_ERROR_INVALID_ARGUMENT on invalid cipher input
+     sizes (instead of PSA_ERROR_BAD_STATE in some cases) to make the
+     psa_cipher_* functions compliant with the PSA Crypto API specification.
+   * mbedtls_ecp_curve_list() now lists Curve25519 and Curve448 under the names
+     "x25519" and "x448". These curves support ECDH but not ECDSA. If you need
+     only the curves that support ECDSA, filter the list with
+     mbedtls_ecdsa_can_do().
+   * Fix psa_generate_key() returning an error when asked to generate
+     an ECC key pair on Curve25519 or secp244k1.
+   * Fix psa_key_derivation_output_key() to allow the output of a combined key
+     agreement and subsequent key derivation operation to be used as a key
+     inside of the PSA Crypto core.
+   * Fix handling of EOF against 0xff bytes and on platforms with unsigned
+     chars. Fixes a build failure on platforms where char is unsigned. Fixes
+     #3794.
+   * Fix an off-by-one error in the additional data length check for
+     CCM, which allowed encryption with a non-standard length field.
+     Fixes #3719.
+   * Correct the default IV size for mbedtls_cipher_info_t structures using
+     MBEDTLS_MODE_ECB to 0, since ECB mode ciphers don't use IVs.
+   * Make arc4random_buf available on NetBSD and OpenBSD when _POSIX_C_SOURCE is
+     defined. Fix contributed in #3571.
+   * Fix conditions for including string.h in error.c. Fixes #3866.
+   * psa_set_key_id() now also sets the lifetime to persistent for keys located
+     in a secure element.
+   * Attempting to create a volatile key with a non-zero key identifier now
+     fails. Previously the key identifier was just ignored when creating a
+     volatile key.
+   * Attempting to create or register a key with a key identifier in the vendor
+     range now fails.
+   * Fix build failures on GCC 11. Fixes #3782.
+   * Add missing arguments of debug message in mbedtls_ssl_decrypt_buf.
+   * Fix a memory leak in mbedtls_mpi_sub_abs() when the result was negative
+     (an error condition) and the second operand was aliased to the result.
+   * Fix a case in elliptic curve arithmetic where an out-of-memory condition
+     could go undetected, resulting in an incorrect result.
+   * In CTR_DRBG and HMAC_DRBG, don't reset the reseed interval in seed().
+     Fixes #2927.
+   * In PEM writing functions, fill the trailing part of the buffer with null
+     bytes. This guarantees that the corresponding parsing function can read
+     the buffer back, which was the case for mbedtls_x509write_{crt,csr}_pem
+     until this property was inadvertently broken in Mbed TLS 2.19.0.
+     Fixes #3682.
+   * Fix a build failure that occurred with the MBEDTLS_AES_SETKEY_DEC_ALT
+     option on. In this configuration key management methods that are required
+     for MBEDTLS_CIPHER_MODE_XTS were excluded from the build and made it fail.
+     Fixes #3818. Reported by John Stroebel.
+
+Changes
+   * Reduce stack usage significantly during sliding window exponentiation.
+     Reported in #3591 and fix contributed in #3592 by Daniel Otte.
+   * The PSA persistent storage format is updated to always store the key bits
+     attribute. No automatic upgrade path is provided. Previously stored keys
+     must be erased, or manually upgraded based on the key storage format
+     specification (docs/architecture/mbed-crypto-storage-specification.md).
+     Fixes #3740.
+   * Remove the zeroization of a pointer variable in AES rounds. It was valid
+     but spurious and misleading since it looked like a mistaken attempt to
+     zeroize the pointed-to buffer. Reported by Antonio de la Piedra, CEA
+     Leti, France.

+### Entropy collection entry point
+
+A driver can declare an entropy source by providing a `"get_entropy"` entry point. This entry point has the following prototype for a driver with the prefix `"acme"`:
+
+```
+psa_status_t acme_get_entropy(uint32_t flags,
+                              size_t *estimate_bits,
+                              uint8_t *output,
+                              size_t output_size);
+```
+
+The semantics of the parameters is as follows:
+
+* `flags`: a bit-mask of [entropy collection flags](#entropy-collection-flags).
+* `estimate_bits`: on success, an estimate of the amount of entropy that is present in the `output` buffer, in bits. This must be at least `1` on success. The value is ignored on failure. Drivers should return a conservative estimate, even in circumstances where the quality of the entropy source is degraded due to environmental conditions (e.g. undervolting, low temperature, etc.).
+* `output`: on success, this buffer contains non-deterministic data with an estimated entropy of at least `*estimate_bits` bits. When the entropy is coming from a hardware peripheral, this should preferably be raw or lightly conditioned measurements from a physical process, such that statistical tests run over a sufficiently large amount of output can confirm the entropy estimates. But this specification also permits entropy sources that are fully conditioned, for example when the PSA Cryptography system is running as an application in an operating system and `"get_entropy"` returns data from the random generator in the operating system's kernel.
+* `output_size`: the size of the `output` buffer in bytes. This size should be large enough to allow a driver to pass unconditioned data with a low density of entropy; for example a peripheral that returns eight bytes of data with an estimated one bit of entropy cannot provide meaningful output in less than 8 bytes.
+
+Note that there is no output parameter indicating how many bytes the driver wrote to the buffer. Such an output length indication is not necessary because the entropy may be located anywhere in the buffer, so the driver may write less than `output_size` bytes but the core does not need to know this. The output parameter `estimate_bits` contains the amount of entropy, expressed in bits, which may be significantly less than `output_size * 8`.
+
+The entry point may return the following statuses:
+
+* `PSA_SUCCESS`: success. The output buffer contains some entropy.
+* `PSA_ERROR_INSUFFICIENT_ENTROPY`: no entropy is available without blocking. This is only permitted if the `PSA_DRIVER_GET_ENTROPY_BLOCK` flag is clear. The core may call `get_entropy` again later, giving time for entropy to be gathered or for adverse environmental conditions to be rectified.
+* Other error codes indicate a transient or permanent failure of the entropy source.
+
+Unlike most other entry points, if multiple transparent drivers include a `"get_entropy"` point, the core will call all of them (as well as the entry points from opaque drivers). Fallback is not applicable to `"get_entropy"`.
+
+#### Entropy collection flags
+
+* `PSA_DRIVER_GET_ENTROPY_BLOCK`: If this flag is set, the driver should block until it has at least one bit of entropy. If this flag is clear, the driver should avoid blocking if no entropy is readily available.
+* `PSA_DRIVER_GET_ENTROPY_KEEPALIVE`: This flag is intended to help with energy management for entropy-generating peripherals. If this flag is set, the driver should expect another call to `acme_get_entropy` after a short time. If this flag is clear, the core is not expecting to call the `"get_entropy"` entry point again within a short amount of time (but it may do so nonetheless).
+
+#### Entropy collection and blocking
+
+The intent of the `BLOCK` and `KEEPALIVE` [flags](#entropy-collection-flags) is to support drivers for TRNG (True Random Number Generator, i.e. an entropy source peripheral) that have a long ramp-up time, especially on platforms with multiple entropy sources.
+
+Here is a suggested call sequence for entropy collection that leverages these flags:
+
+1. The core makes a first round of calls to `"get_entropy"` on every source with the `BLOCK` flag clear and the `KEEPALIVE` flag set, so that drivers can prepare the TRNG peripheral.
+2. The core makes a second round of calls with the `BLOCK` flag set and the `KEEPALIVE` flag clear to gather needed entropy.
+3. If the second round does not collect enough entropy, the core makes more similar rounds, until the total amount of collected entropy is sufficient.

+### Random generation entry points
+
+A transparent driver may provide an operation family that can be used as a cryptographic random number generator. The random generation mechanism must obey the following requirements:
+
+* The random output must be of cryptographic quality, with a uniform distribution. Therefore, if the random generator includes an entropy source, this entropy source must be fed through a CSPRNG (cryptographically secure pseudo-random number generator).
+* Random generation is expected to be fast. (If a device can provide entropy but is slow at generating random data, declare it as an [entropy driver](#entropy-collection-entry-point) instead.)
+* The random generator should be able to incorporate entropy provided by an outside source. If it isn't, the random generator can only be used if it's the only entropy source on the platform. (A random generator peripheral can be declared as an [entropy source](#entropy-collection-entry-point) instead of a random generator; this way the core will combine it with other entropy sources.)
+* The random generator may either be deterministic (in the sense that it always returns the same data when given the same entropy inputs) or non-deterministic (including its own entropy source). In other words, this interface is suitable both for PRNG (pseudo-random number generator, also known as DRBG (deterministic random bit generator)) and for NRBG (non-deterministic random bit generator).
+
+If no driver implements the random generation entry point family, the core provides an unspecified random generation mechanism.
+
+This operation family requires the following type, entry points and parameters (TODO: where exactly are the parameters in the JSON structure?):
+
+* Type `"random_context_t"`: the type of a random generation context.
+* `"init_random"` (entry point, optional): if this function is present, [the core calls it once](#random-generator-initialization) after allocating a `"random_context_t"` object.
+* `"add_entropy"` (entry point, optional): the core calls this function to [inject entropy](#entropy-injection). This entry point is optional if the driver is for a peripheral that includes an entropy source of its own, however [random generator drivers without entropy injection](#random-generator-drivers-without-entropy-injection) have limited portability since they can only be used on platforms with no other entropy source. This entry point is mandatory if `"initial_entropy_size"` is nonzero.
+* `"get_random"` (entry point, mandatory): the core calls this function whenever it needs to [obtain random data](#the-get_random-entry-point).
+* `"initial_entropy_size"` (integer, mandatory): the minimum number of bytes of entropy that the core must supply before the driver can output random data. This can be `0` if the driver is for a peripheral that includes an entropy source of its own.
+* `"reseed_entropy_size"` (integer, optional): the minimum number of bytes of entropy that the core should supply via [`"add_entropy"`](#entropy-injection) when the driver runs out of entropy. This value is also a hint for the size to supply if the core makes additional calls to `"add_entropy"`, for example to enforce prediction resistance. If omitted, the core should pass an amount of entropy corresponding to the expected security strength of the device (for example, pass 32 bytes of entropy when reseeding to achieve a security strength of 256 bits). If specified, the core should pass the larger of `"reseed_entropy_size"` and the amount corresponding to the security strength.
+
+Random generation is not parametrized by an algorithm. The choice of algorithm is up to the driver.
+
+#### Random generator initialization
+
+The `"init_random"` entry point has the following prototype for a driver with the prefix `"acme"`:
+
+```
+psa_status_t acme_init_random(acme_random_context_t *context);
+```
+
+The core calls this entry point once after allocating a random generation context. Initially, the context object is all-bits-zero.
+
+If a driver does not have an `"init_random"` entry point, the context object passed to the first call to `"add_entropy"` or `"get_random"` will be all-bits-zero.
+
+#### Entropy injection
+
+The `"add_entropy"` entry point has the following prototype for a driver with the prefix `"acme"`:
+
+```
+psa_status_t acme_add_entropy(acme_random_context_t *context,
+                              const uint8_t *entropy,
+                              size_t entropy_size);
+```
+
+The semantics of the parameters is as follows:
+
+* `context`: a random generation context. On the first call to `"add_entropy"`, this object has been initialized by a call to the driver's `"init_random"` entry point if one is present, and to all-bits-zero otherwise.
+* `entropy`: a buffer containing full-entropy data to seed the random generator. “Full-entropy” means that the data is uniformly distributed and independent of any other observable quantity.
+* `entropy_size`: the size of the `entropy` buffer in bytes. It is guaranteed to be at least `1`, but it may be smaller than the amount of entropy that the driver needs to deliver random data, in which case the core will call the `"add_entropy"` entry point again to supply more entropy.
+
+The core calls this function to supply entropy to the driver. The driver must mix this entropy into its internal state. The driver must mix the whole supplied entropy, even if there is more than what the driver requires, to ensure that all entropy sources are mixed into the random generator state. The driver may mix additional entropy of its own.
+
+The core may call this function at any time. For example, to enforce prediction resistance, the core can call `"add_entropy"` immediately after each call to `"get_random"`. The core must call this function in two circumstances:
+
+* Before the first call to the `"get_random"` entry point, to supply `"initial_entropy_size"` bytes of entropy.
+* After a call to the `"get_random"` entry point returns less than the required amount of random data, to supply at least `"reseed_entropy_size"` bytes of entropy.
+
+When the driver requires entropy, the core can supply it with one or more successive calls to the `"add_entropy"` entry point. If the required entropy size is zero, the core does not need to call `"add_entropy"`.
+
+#### Combining entropy sources with a random generation driver
+
+This section provides guidance on combining one or more [entropy sources](#entropy-collection-entry-point) (each having a `"get_entropy"` entry point) with a random generation driver (with an `"add_entropy"` entry point).
+
+Note that `"get_entropy"` returns data with an estimated amount of entropy that is in general less than the buffer size. The core must apply a mixing algorithm to the output of `"get_entropy"` to obtain full-entropy data.
+
+For example, the core may use a simple mixing scheme based on a pseudorandom function family $(F_k)$ with an $E$-bit output where $E = 8 \cdot \mathtt{entropy_size}$ and $\mathtt{entropy_size}$ is the desired amount of entropy in bytes (typically the random driver's `"initial_entropy_size"` property for the initial seeding and the `"reseed_entropy_size"` property for subsequent reseeding). The core calls the `"get_entropy"` points of the available entropy drivers, outputting a string $s_i$ and an entropy estimate $e_i$ on the $i$th call. It does so until the total entropy estimate $e_1 + e_2 + \ldots + e_n$ is at least $E$. The core then calculates $F_k(0)$ where $k = s_1 || s_2 || \ldots || s_n$. This value is a string of $\mathtt{entropy_size}$, and since $(F_k)$ is a pseudorandom function family, $F_k(0)$ is uniformly distributed over strings of $\mathtt{entropy_size}$ bytes. Therefore $F_k(0)$ is a suitable value to pass to `"add_entropy"`.
+
+Note that the mechanism above is only given as an example. Implementations may choose a different mechanism, for example involving multiple pools or intermediate compression functions.
+
+#### Random generator drivers without entropy injection
+
+Random generator drivers should have the capability to inject additional entropy through the `"add_entropy"` entry point. This ensures that the random generator depends on all the entropy sources that are available on the platform. A driver where a call to `"add_entropy"` does not affect the state of the random generator is not compliant with this specification.
+
+However, a driver may omit the `"add_entropy"` entry point. This limits the driver's portability: implementations of the PSA Cryptography specification may reject drivers without an `"add_entropy"` entry point, or only accept such drivers in certain configurations. In particular, the `"add_entropy"` entry point is required if:
+
+* the integration of PSA Cryptography includes an entropy source that is outside the driver; or
+* the core saves random data in persistent storage to be preserved across platform resets.
+
+#### The `"get_random"` entry point
+
+The `"get_random"` entry point has the following prototype for a driver with the prefix `"acme"`:
+
+```
+psa_status_t acme_get_random(acme_random_context_t *context,
+                             uint8_t *output,
+                             size_t output_size,
+                             size_t *output_length);
+```
+
+The semantics of the parameters is as follows:
+
+* `context`: a random generation context. If the driver's `"initial_entropy_size"` property is nonzero, the core must have called `"add_entropy"` at least once with a total of at least `"initial_entropy_size"` bytes of entropy before it calls `"get_random"`. Alternatively, if the driver's `"initial_entropy_size"` property is zero and the core did not call `"add_entropy"`, or if the driver has no `"add_entropy"` entry point, the core must have called `"init_random"` if present, and otherwise the context is all-bits zero.
+* `output`: on success (including partial success), the first `*output_length` bytes of this buffer contain cryptographic-quality random data. The output is not used on error.
+* `output_size`: the size of the `output` buffer in bytes.
+* `*output_length`: on success (including partial success), the number of bytes of random data that the driver has written to the `output` buffer. This is preferably `output_size`, but the driver is allowed to return less data if it runs out of entropy as described below. The core sets this value to 0 on entry. The value is not used on error.
+
+The driver may return the following status codes:
+
+* `PSA_SUCCESS`: the `output` buffer contains `*output_length` bytes of cryptographic-quality random data. Note that this may be less than `output_size`; in this case the core should call the driver's `"add_entropy"` method to supply at least `"reseed_entropy_size"` bytes of entropy before calling `"get_random"` again.
+* `PSA_ERROR_INSUFFICIENT_ENTROPY`: the core must supply additional entropy by calling the `"add_entropy"` entry point with at least `"reseed_entropy_size"` bytes.
+* `PSA_ERROR_NOT_SUPPORTED`: the random generator is not available. This is only permitted if the driver specification for random generation has the [fallback property](#fallback) enabled.
+* Other error codes such as `PSA_ERROR_COMMUNICATION_FAILURE` or `PSA_ERROR_HARDWARE_FAILURE` indicate a transient or permanent error.
+
 ### Fallback
 
 Sometimes cryptographic accelerators only support certain cryptographic mechanisms partially. The capability description language allows specifying some restrictions, including restrictions on key sizes, but it cannot cover all the possibilities that may arise in practice. Furthermore, it may be desirable to deploy the same binary image on different devices, only some of which have a cryptographic accelerators.

 ## Open questions
 
+### Value representation

+
+This choice is partly driven by the use of the values, so they might not be uniform. Note that if the value can be zero and it's plausible that the core would want to statically allocate an array of the given size, the core needs to know whether the value is 0 so that it could use code like
