 @subsubheading Overriding specific algorithms
 When an optimized implementation of a single algorithm is available,
 say a hardware assisted version of @acronym{AES-CBC} then the
-following (internal) functions, from @code{crypto-backend.h}, can 
+following functions, from @code{crypto.h}, can 
 be used to register those algorithms.
 
 @itemize
 
-@item @code{gnutls_crypto_single_cipher_register}:

 To register a cipher algorithm.
 
-@item @code{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.
 
-@subsubheading Overriding the cryptographic library
-In some systems, that might contain a broad acceleration engine, it 
-might be desirable to override big parts of the cryptographic back-end, 
-or even all of them. The following functions are provided for this reason.
-
-@itemize
-
-@item @code{gnutls_crypto_cipher_register}:
-To override the cryptographic algorithms back-end.
-
-@item @code{gnutls_crypto_digest_register}:
-To override the digest algorithms back-end.
-
-@item @code{gnutls_crypto_rnd_register}:
-To override the random number generator back-end.
-
-@item @code{gnutls_crypto_bigint_register}:
-To override the big number number operations back-end.
-
-@item @code{gnutls_crypto_pk_register}:
-To override the public key encryption back-end. This is tied to the
-big number operations so either none or both of them should be overridden.
