12.6.1 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_register2 To register a cipher algorithm.
• gnutls_crypto_single_mac_register2 To register a MAC algorithm.

  gnutls_crypto_single_digest_register2 To register a digest (hash) algorithm.

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