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.
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
