NAME
       gnutls_crypto_register_cipher - API function

SYNOPSIS
       #include <gnutls/crypto.h>

       int gnutls_crypto_register_cipher(gnutls_cipher_algorithm_t algorithm,
       int priority, gnutls_cipher_init_func init, gnutls_cipher_setkey_func
       setkey, gnutls_cipher_setiv_func setiv, gnutls_cipher_encrypt_func
       encrypt, gnutls_cipher_decrypt_func decrypt, gnutls_cipher_deinit_func
       deinit);

ARGUMENTS
       gnutls_cipher_algorithm_t algorithm
                   is the gnutls algorithm identifier

       int priority
                   is the priority of the algorithm

       gnutls_cipher_init_func init
                   A function which initializes the cipher

       gnutls_cipher_setkey_func setkey
                   A function which sets the key of the cipher

       gnutls_cipher_setiv_func setiv
                   A function which sets the nonce/IV of the cipher (non-AEAD)

       gnutls_cipher_encrypt_func encrypt
                   A function which performs encryption (non-AEAD)

       gnutls_cipher_decrypt_func decrypt
                   A function which performs decryption (non-AEAD)

       gnutls_cipher_deinit_func deinit
                   A function which deinitializes the cipher

DESCRIPTION
       This function will register a cipher algorithm to be used by gnutls.
       Any algorithm registered will override the included algorithms and by
       convention kernel implemented algorithms have priority of 90 and
       CPU-assisted of 80.  The algorithm with the lowest priority will be
       used by gnutls.

       In the case the registered init or setkey functions return
       GNUTLS_E_NEED_FALLBACK, GnuTLS will attempt to use the next in priority
       registered cipher.

       The functions which are marked as non-AEAD they are not required when
       registering a cipher to be used with the new AEAD API introduced in
       GnuTLS 3.4.0. Internally GnuTLS uses the new AEAD API.

RETURNS
       GNUTLS_E_SUCCESS on success, otherwise a negative error code.

SINCE
       3.4.0
