NAME

gnutls_x509_privkey_get_key_id - Return unique ID of the key's parameters  

SYNOPSIS

#include <gnutls/x509.h>

int gnutls_x509_privkey_get_key_id(gnutls_x509_privkey_t key, unsigned int flags, unsigned char * output_data, size_t * output_data_size);  

ARGUMENTS

gnutls_x509_privkey_t key
Holds the key
unsigned int flags
should be 0 for now
unsigned char * output_data
will contain the key ID
size_t * output_data_size
holds the size of output_data (and will be replaced by the actual size of parameters)
 

DESCRIPTION

This function will return a unique ID the depends on the public key parameters. This ID can be used in checking whether a certificate corresponds to the given key.

If the buffer provided is not long enough to hold the output, then *output_data_size is updated and GNUTLS_E_SHORT_MEMORY_BUFFER will be returned. The output will normally be a SHA-1 hash output, which is 20 bytes.  

RETURNS

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