NAME

       gnutls_crypto_register_aead_cipher - API function

SYNOPSIS

       #include <gnutls/crypto.h>

       int     gnutls_crypto_register_aead_cipher(gnutls_cipher_algorithm_t     algorithm,     int     priority,
       gnutls_cipher_init_func   init,   gnutls_cipher_setkey_func    setkey,    gnutls_cipher_aead_encrypt_func
       aead_encrypt, gnutls_cipher_aead_decrypt_func aead_decrypt, gnutls_cipher_deinit_func deinit);

ARGUMENTS

       gnutls_cipher_algorithm_t algorithm
                   is the gnutls AEAD cipher 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_aead_encrypt_func aead_encrypt
                   Perform the AEAD encryption

       gnutls_cipher_aead_decrypt_func aead_decrypt
                   Perform the AEAD decryption

       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 registered will be used with the new AEAD API introduced in GnuTLS 3.4.0. Internally GnuTLS
       uses the new AEAD API.

DEPRECATED

       since 3.7.0 it is no longer possible to override cipher implementation

RETURNS

       GNUTLS_E_SUCCESS on success, otherwise a negative error code.

SINCE

       3.4.0
