gnutls_cipher_decrypt2(3)	    gnutls	     gnutls_cipher_decrypt2(3)

NAME
       gnutls_cipher_decrypt2 -	API function

SYNOPSIS
       #include	<gnutls/crypto.h>

       int  gnutls_cipher_decrypt2(gnutls_cipher_hd_t  handle,	const  void  *
       ctext, size_t ctext_len,	void * ptext, size_t ptext_len);

ARGUMENTS
       gnutls_cipher_hd_t handle
		   is a	gnutls_cipher_hd_t type

       const void * ctext
		   the data to decrypt

       size_t ctext_len
		   the length of data to decrypt

       void * ptext
		   the decrypted data

       size_t ptext_len
		   the available length	for decrypted data

DESCRIPTION
       This function will decrypt the given data using the algorithm specified
       by the context. For block ciphers the  ctext_len	must be	a multiple  of
       the  block  size.  For  the supported ciphers the plaintext data	length
       will equal the ciphertext size.

       Note that in AEAD ciphers, this will not	check the tag. You  will  need
       to  compare  the	 tag  sent  with  the  value  returned from gnutls_ci-
       pher_tag().

RETURNS
       Zero or a negative error	code on	error.

SINCE
       2.12.0
