gnutls_crypto_register_cipher − API function

#include<gnutls/crypto.h>

, int int
gnutls_crypto_register_cipher(gnutls_cipher_algorithm_t
algorithm



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

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.

GNUTLS_E_SUCCESS on success, otherwise a negative error
code.
