@deftypefun {int} {gnutls_cipher_init} (gnutls_cipher_hd_t * @var{handle}, gnutls_cipher_algorithm_t @var{cipher}, const gnutls_datum_t * @var{key}, const gnutls_datum_t * @var{iv})
@var{handle}: is a @code{gnutls_cipher_hd_t}  type

@var{cipher}: the encryption algorithm to use

@var{key}: the key to be used for encryption/decryption

@var{iv}: the IV to use (if not applicable set NULL)

This function will initialize the  @code{handle} context to be usable
for encryption/decryption of data. This will effectively use the
current crypto backend in use by gnutls or the cryptographic
accelerator in use.

@strong{Returns:} Zero or a negative error code on error.

@strong{Since:} 2.10.0
