SYNOPSIS

9       #include <gnutls/crypto.h>
10
11       int  gnutls_cipher_decrypt(gnutls_cipher_hd_t  handle,  void  *  ctext,
12       size_t ctext_len);
13

ARGUMENTS

15       gnutls_cipher_hd_t handle
16                   is a gnutls_cipher_hd_t type
17
18       void * ctext
19                   the data to decrypt
20
21       size_t ctext_len
22                   the length of data to decrypt
23

28       Note  that  in AEAD ciphers, this will not check the tag. You will need
29       to   compare   the   tag   sent   with   the   value   returned    from
30       gnutls_cipher_tag().
