gnutls_cipher_encrypt3(3)	    gnutls	     gnutls_cipher_encrypt3(3)

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 maxi-
		   mum 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 ci-
       pher 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.

SINCE
       3.7.7
