gnutls_privkey_decrypt_data23
Api function
Usage
#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 |

|
a preallocated buffer that will be filled with the plaintext |
size_t plaintext_size
|
in/out size of the plaintext |
