- * Authenticates and encrypts a message using AES in CCM mode. Please
- * see also RFC 3610 for the meaning of \p M, \p L, \p lm and \p la.
- * 
- * \param ctx The initialized rijndael_ctx object to be used for AES operations.
- * \param M   The number of authentication octets.
- * \param L   The number of bytes used to encode the message length.
- * \param N   The nonce value to use. You must provide \c DTLS_CCM_BLOCKSIZE 
- *            nonce octets, although only the first \c 16 - \p L are used.
- * \param msg The message to encrypt. The first \p la octets are additional
- *            authentication data that will be cleartext. Note that the 
- *            encryption operation modifies the contents of \p msg and adds 
- *            \p M bytes MAC. Therefore, the buffer must be at least
- *            \p lm + \p M bytes large.
- * \param lm  The actual length of \p msg.
- * \param aad A pointer to the additional authentication data (can be \c NULL if
- *            \p la is zero).
- * \param la  The number of additional authentication octets (may be zero).
