Аргументы (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
Описание (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.
Устарело (Deprecated)
since 3.7.0 it is no longer possible to override cipher
implementation
Возвращаемое значение (Return value)
GNUTLS_E_SUCCESS
on success, otherwise a negative error code.
