Hanno Becker 27a2688fbb Introduce public macro for maximum symmetric cipher key length ... This commit introduces the public macro MBEDTLS_MAX_KEY_LENGTH, which evaluates to an upper bound for the key lengths of all enabled ciphers, in Bytes. This is analogous to the already existing macros MBEDTLS_MAX_IV_LENGTH and MBEDTLS_MAX_BLOCK_LENGTH, which provide upper bounds for the IV and block length, respectively. For now, MBEDTLS_MAX_KEY_LENGTH is 32 Bytes by default, and 64 in case XTS is enabled. This is a strict overapproximation for some restricted configurations. Ideally, the upper bound should be calculated exactly and automatically from the list of enabled ciphers. The same applies to the existing macros MBEDTLS_MAX_IV_LENGTH and MBEDTLS_MAX_BLOCK_LENGTH, though, and is left for future work.
