NAME

       gnutls_cipher_init - API function

SYNOPSIS

       #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);

ARGUMENTS

       gnutls_cipher_hd_t * handle
                   is a gnutls_cipher_hd_t type

       gnutls_cipher_algorithm_t cipher
                   the encryption algorithm to use

       const gnutls_datum_t * key
                   the key to be used for encryption/decryption

       const gnutls_datum_t * iv
                   the IV to use (if not applicable set NULL)

DESCRIPTION

       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.

RETURNS

       Zero or a negative error code on error.

SINCE

       2.10.0
