NAME         top

       gnutls_privkey_decrypt_data2 - API function

SYNOPSIS         top

       #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         top

       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

       size_t plaintext_size
                   in/out size of the plaintext

DESCRIPTION         top

       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         top

       On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative
       error value.
