NAME
       gnutls_aead_cipher_encrypt - API	function

SYNOPSIS
       #include	<gnutls/crypto.h>

       int  gnutls_aead_cipher_encrypt(gnutls_aead_cipher_hd_t	handle,	 const
       void * nonce, size_t nonce_len, const void  *  auth,  size_t  auth_len,
       size_t  tag_size,  const	 void *	ptext, size_t ptext_len, void *	ctext,
       size_t *	ctext_len);

ARGUMENTS
       gnutls_aead_cipher_hd_t handle
		   is a	gnutls_aead_cipher_hd_t	type.

       const void * nonce

       size_t ptext_len
		   The length of data to encrypt

       void * ctext
		   the encrypted data including	authentication tag

       size_t *	ctext_len
		   the length of encrypted data	(initially must	hold the maxi-
		   mum available size, including space for tag)

DESCRIPTION
       This function will encrypt the given data using the algorithm specified
       by the context. The output data will contain the	authentication tag.
