Имя (Name)

gnutls_pubkey_get_key_id - API function

Синопсис (Synopsis)

#include <gnutls/abstract.h>

       int gnutls_pubkey_get_key_id(gnutls_pubkey_t key, unsigned int
       flags, unsigned char * output_data, size_t * output_data_size);

Аргументы (Arguments)

gnutls_pubkey_t key
                   Holds the public key

       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 public 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.
