gnutls_cipher_decrypt(3)            gnutls            gnutls_cipher_decrypt(3)

NAME
       gnutls_cipher_decrypt - API function

SYNOPSIS
       #include <gnutls/crypto.h>

       int gnutls_cipher_decrypt(gnutls_cipher_hd_t handle, void * ctext,
       size_t ctext_len);

ARGUMENTS
       gnutls_cipher_hd_t handle
                   is a gnutls_cipher_hd_t type

       void * ctext
                   the data to decrypt

       size_t ctext_len
                   the length of data to decrypt

DESCRIPTION
       This function will decrypt the given data using the algorithm specified
       by the context.

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

RETURNS
       Zero or a negative error code on error.

SINCE
       2.10.0
