NAME         top

       gnutls_crypto_register_aead_cipher - API function

SYNOPSIS         top

       #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         top

       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         top

       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.

RETURNS         top

       GNUTLS_E_SUCCESS on success, otherwise a negative error code.
