NAME
gnutls_aead_cipher_decryptv2 - API function

SYNOPSIS
#include <gnutls/crypto.h>

int gnutls_aead_cipher_decryptv2(gnutls_aead_cipher_hd_t handle, const void * nonce, size_t nonce_len, const giovec_t * auth_iov, int auth_iovcnt, const giovec_t * iov, int iovcnt, void * tag, size_t tag_size);

ARGUMENTS

gnutls_aead_cipher_hd_t handle
    is a gnutls_aead_cipher_hd_t type.

const void * nonce
    the nonce to set

size_t nonce_len
    The length of the nonce

const giovec_t * auth_iov
    additional data to be authenticated

int auth_iovcnt
    The number of buffers in auth_iov

const giovec_t * iov
    the data to decrypt

int iovcnt
    The number of buffers in iov

void * tag
    The authentication tag

size_t tag_size
    The size of the tag to use (use zero for the default)

DESCRIPTION
This is similar to gnutls_aead_cipher_decrypt(), but it performs in-place encryption on the provided data buffers.
