@deftypefun {int} {gnutls_cipher_decrypt3} (gnutls_cipher_hd_t @var{handle}, const void * @var{ctext}, size_t @var{ctext_len}, void * @var{ptext}, size_t * @var{ptext_len}, unsigned @var{flags})
@var{handle}: is a @code{gnutls_cipher_hd_t}  type

@var{ctext}: the data to decrypt

@var{ctext_len}: the length of data to decrypt

@var{ptext}: the decrypted data

@var{ptext_len}: the available length for decrypted data

@var{flags}: flags for padding

This function will decrypt the given data using the algorithm
specified by the context. If  @code{flags} is specified, padding for the
decrypted data will be removed accordingly and  @code{ptext_len} will be
updated.

@strong{Returns:} Zero or a negative error code on error.

@strong{Since:} 3.7.7
