NAME
gnutls_x509_crq_get_key_id - API function
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
a certificate of type gnutls_x509_crq_t
unsigned int flags
should be one of the flags from gnutls_keyid_flags_t
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 that depends on the public key
parameters. This ID can be used in checking whether a certificate cor-
responds 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.
RETURNS
In case of failure a negative error code will be returned, and 0 on
success.
SINCE
2.8.0
