gnutls_cipher_init - API function

#include <gnutls/crypto.h>

int gnutls_cipher_init(gnutls_cipher_hd_t * handle, gnutls_cipher_algorithm_t cipher, const gnutls_datum_t * key, const gnutls_datum_t * iv);

is a gnutls_cipher_hd_t type
the encryption algorithm to use
the key to be used for encryption/decryption
the IV to use (if not applicable set NULL)

This function will initialize the 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.
