@deftypefun {int} {gnutls_cipher_encrypt2} (gnutls_cipher_hd_t @var{handle}, const void * @var{ptext}, size_t @var{ptext_len}, void * @var{ctext}, size_t @var{ctext_len})
@var{handle}: is a @code{gnutls_cipher_hd_t}  type

@var{ptext}: the data to encrypt

@var{ptext_len}: the length of data to encrypt

@var{ctext}: the encrypted data

@var{ctext_len}: the available length for encrypted data

This function will encrypt the given data using the algorithm
specified by the context. For block ciphers the  @code{ptext_len} must be
a multiple of the block size. For the supported ciphers the encrypted
data length will equal the plaintext size.

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

@strong{Since:} 2.12.0
