gnutls_crypto_register_aead_cipher − API function


, int int

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

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

GNUTLS_E_SUCCESS on success, otherwise a negative error
