12 int gnutls_x509_crq_get_key_id(gnutls_x509_crq_t crq, unsigned int
13 flags, unsigned char * output_data, size_t * output_data_size);
14
16 gnutls_x509_crq_t crq
17 Holds the certificate signing request
18
19 unsigned int flags
20 should be 0 for now
21
22 unsigned char * output_data
23 will contain the key ID
24
25 size_t * output_data_size
26 holds the size of output_data (and will be replaced by the
27 actual size of parameters)
28
30 This function will return a unique ID the depends on the public key
31 parameters. This ID can be used in checking whether a certificate cor‐
32 responds to the given private key.
33
34 If the buffer provided is not long enough to hold the output, then
35 *output_data_size is updated and GNUTLS_E_SHORT_MEMORY_BUFFER will be
36 returned. The output will normally be a SHA-1 hash output, which is 20
37 bytes.
38
40 In case of failure a negative value will be returned, and 0 on success.
