gnutls_pubkey_get_key_id(3)	    gnutls	   gnutls_pubkey_get_key_id(3)

NAME
       gnutls_pubkey_get_key_id	- API function

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);

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)

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  cor-
       responds	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.

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

SINCE
       2.12.0
