+--

+
+3DES has weaknesses/limitations and there are better alternatives, and more and

+
+The migration path here is to chose from the recomended in literature alternatives.

+CCM interface changes: impact for alternative implementations
+-------------------------------------------------------------
+
+The CCM interface has changed with the addition of support for
+multi-part operations. Five new API functions have been defined:
+mbedtls_ccm_starts(), mbedtls_ccm_set_lengths(),
+mbedtls_ccm_update_ad(), mbedtls_ccm_update() and mbedtls_ccm_finish().
+Alternative implementations of CCM (`MBEDTLS_CCM_ALT`) have now to
+implement those additional five API functions.

+Calling `mbedtls_cipher_finish()` is mandatory for all multi-part operations
+----------------------------------------------------------------------------
+
+This only affects people who use the cipher module to perform AEAD operations
+using the multi-part API.
+
+Previously, the documentation didn't state explicitly if it was OK to call
+`mbedtls_cipher_check_tag()` or `mbedtls_cipher_write_tag()` directly after
+the last call to `mbedtls_cipher_update()` - that is, without calling
+`mbedtls_cipher_finish()` in-between. If you code was missing that call,
+please add it and be prepared to get as much as 15 bytes of output.
+
+Currently the output is always 0 bytes, but it may be more when alternative
+implementations of the underlying primitives are in use, or with future
+versions of the library.

+`mbedtlsl_ssl_conf_psk()` and `mbedtls_ssl_conf_psk_opaque()`
+multiple times on the same SSL configuration.
+
+In Mbed TLS 2.x, users would observe later calls overwriting

+To achieve equivalent functionality when migrating to Mbed TLS 3.0,

+`mbedtls_ssl_conf_psk()` _or_ `mbedtls_ssl_conf_psk_opaque()`

+This option was a trade-off between functionality and code size: it allowed

+ * \brief           This function feeds an input buffer into an ongoing CCM
+ *                  encryption or decryption operation.
+ *
+ *                  You may call this function zero, one or more times
+ *                  to pass successive parts of the input: the plaintext to
+ *                  encrypt, or the ciphertext (not including the tag) to
+ *                  decrypt. After the last part of the input, call
+ *                  mbedtls_ccm_finish(). The lengths \p input_len of the
+ *                  data parts should eventually add up exactly to the
+ *                  plaintext length \c plaintext_len passed to
+ *                  mbedtls_ccm_set_lengths().
+ *
+ *                  This function may produce output in one of the following
+ *                  ways:
+ *                  - Immediate output: the output length is always equal
+ *                    to the input length.
+ *                  - Buffered output: except for the last part of input data,
+ *                    the output consists of a whole number of 16-byte blocks.
+ *                    If the total input length so far (not including
+ *                    associated data) is 16 \* *B* + *A* with *A* < 16 then
+ *                    the total output length is 16 \* *B*.
+ *                    For the last part of input data, the output length is
+ *                    equal to the input length plus the number of bytes (*A*)
+ *                    buffered in the previous call to the function (if any).
+ *                    The function uses the plaintext length
+ *                    \c plaintext_len passed to mbedtls_ccm_set_lengths()
+ *                    to detect the last part of input data.
+ *
+ *                  In particular:
+ *                  - It is always correct to call this function with
+ *                    \p output_size >= \p input_len + 15.
+ *                  - If \p input_len is a multiple of 16 for all the calls
+ *                    to this function during an operation (not necessary for
+ *                    the last one) then it is correct to use \p output_size
+ *                    =\p input_len.
+ *
+ * \note            This function is not implemented in Mbed TLS yet.
+ *
+ * \param ctx           The CCM context. This must have been started with
+ *                      mbedtls_ccm_starts() and the lengths of the message and

+ *                      mbedtls_ccm_set_lengths().
+ * \param input         The buffer holding the input data. If \p input_len
+ *                      is greater than zero, this must be a readable buffer
+ *                      of at least \p input_len bytes.
+ * \param input_len     The length of the input data in bytes.
+ * \param output        The buffer for the output data. If \p output_size

+ * \param output_size   The size of the output buffer in bytes.
+ *                      See the function description regarding the output size.
