   gnutls_pubkey_get_key_id    ( 3 )

Функции API (API function)

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.
