NAME¶

gnutls_privkey_decrypt_data2 - API function

SYNOPSIS¶

#include <gnutls/abstract.h>

int gnutls_privkey_decrypt_data2(gnutls_privkey_t key, unsigned int flags, const gnutls_datum_t * ciphertext, unsigned char * plaintext, size_t plaintext_size);

ARGUMENTS¶

gnutls_privkey_t key

Holds the key

unsigned int flags

zero for now

const gnutls_datum_t * ciphertext

holds the data to be decrypted

unsigned char * plaintext

a preallocated buffer that will be filled with the plaintext

size_t plaintext_size

in/out size of the plaintext

DESCRIPTION¶

This function will decrypt the given data using the algorithm supported by the private key. Unlike with gnutls_privkey_decrypt_data() this function operates in constant time and constant memory access.

RETURNS¶
