Имя (Name)

gnutls_x509_crt_get_key_id - API function

Синопсис (Synopsis)

#include <gnutls/x509.h>

       int gnutls_x509_crt_get_key_id(gnutls_x509_crt_t crt, unsigned
       int flags, unsigned char * output_data, size_t *
       output_data_size);

Аргументы (Arguments)

gnutls_x509_crt_t crt Holds the certificate

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)

Описание (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 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.

Возвращаемое значение (Return value)

In case of failure a negative error code will be returned, and 0
       on success.
