9.6.2.1 Override specific algorithms

When an optimized implementation of a single algorithm is available, say a hardware assisted version of AES-CBC then the following functions can be used to register those algorithms.

• gnutls_crypto_single_cipher_register To register a cipher algorithm.

  gnutls_crypto_single_digest_register To register a hash (digest) or MAC algorithm.

Those registration functions will only replace the specified algorithm and leave the rest of subsystem intact.
