NAME
gnutls_x509_crq_get_key_id - Return unique ID of public key’s
parameters
SYNOPSIS
#include <gnutls/x509.h>
int gnutls_x509_crq_get_key_id(gnutls_x509_crq_t crq, unsigned int
flags, unsigned char * output_data, size_t * output_data_size);
ARGUMENTS
gnutls_x509_crq_t crq
Holds the certificate signing request
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 private 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.
RETURN VALUE
