NAME
       gnutls_cipher_encrypt3 - API function


SYNOPSIS
       #include <gnutls/crypto.h>

       int   gnutls_cipher_encrypt3(gnutls_cipher_hd_t   handle,   const  void  *  ptext,  size_t
       ptext_len, void * ctext, size_t * ctext_len, unsigned flags);


ARGUMENTS
       gnutls_cipher_hd_t handle
                   is a gnutls_cipher_hd_t type

       const void * ptext
                   the data to encrypt

       size_t ptext_len
                   the length of data to encrypt

       void * ctext
                   the encrypted data

       size_t * ctext_len
                   the length of encrypted data (initially must hold the maximum available size)

       unsigned flags
                   flags for padding


DESCRIPTION
       This function will encrypt the given data using the algorithm specified  by  the  context.
       For  block  ciphers,   ptext_len  is  typically  a multiple of the block size. If not, the
       caller can instruct the function to pad the last block according to  flags  .   Currently,
       the only available padding scheme is GNUTLS_CIPHER_PADDING_PKCS7.

       If   ctext is not NULL, it must hold enough space to store resulting cipher text. To check
       the required size, this function can be called with  ctext set to  NULL.  Then   ctext_len
       will be updated without performing actual encryption.


RETURNS
       Zero or a negative error code on error.
