NAME

       gnutls_pubkey_get_openpgp_key_id - API function

SYNOPSIS

       #include <gnutls/abstract.h>

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

ARGUMENTS

       gnutls_pubkey_t key
                   Holds the public key

       unsigned int flags
                   should be 0 or GNUTLS_PUBKEY_GET_OPENPGP_FINGERPRINT

       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)

       unsigned int * subkey
                   Will be non zero if the key ID corresponds to a subkey

DESCRIPTION

       This function returns the OpenPGP key ID of the corresponding key.  The key is a unique ID  that  depends
       on the public key parameters.

       If  the  flag GNUTLS_PUBKEY_GET_OPENPGP_FINGERPRINT is specified this function returns the fingerprint of
       the master 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 is GNUTLS_OPENPGP_KEYID_SIZE bytes long.

RETURNS

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

SINCE

       3.0
