gnutls_x509_crt_get_key_id: API function
NAMEgnutls_x509_crt_get_key_id - API function
- gnutls_x509_crt_t crt
- Holds the certificate
- 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)
DESCRIPTIONThis function will return a unique ID that 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.
RETURNSIn case of failure a negative error code will be returned, and 0 on success.
