#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);

Holds the key
zero for now
holds the data to be decrypted
a preallocated buffer that will be filled with the plaintext
in/out size of the plaintext

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.
