Initialize a cipher

Synopsis:

#include <qcrypto/qcrypto.h>
int qcrypto_cipher_init(qcrypto_ctx_t *ctx,
                        qcrypto_key_t *key,
                        const qcrypto_cipher_args_t *cargs)

Arguments:

ctx
The algorithm context object.
key
The symmetric key.
cargs
The cipher arguments.
