Actually, it looks that GPGME ignores the validity when listing keys
with SECRET_ONLY flag. Here is a sample program:
#include <stdio.h>
#include <stdlib.h>
#include <locale.h>
#include <gpgme.h>
static gpgme_error_t
list_key_validity (const char *pattern)
{
gpgme_ctx_t ctx;
gpgme_key_t key;
gpgme_error_t err = gpgme_new (&ctx);
int secret_only;
if (err)
goto out;
for (secret_only = 0; secret_only < 2; secret_only++)
{
err = gpgme_op_keylist_start (ctx, pattern, secret_only);
if (err)
goto out;
while (!err)
{
err = gpgme_op_keylist_next (ctx, &key);
if (err)
break;
printf ("%s (%s) revoked = %d, expired = %d\n",
key->subkeys->keyid,
(secret_only ? "sec" : "pub"),
key->subkeys->revoked,
key->subkeys->expired);
gpgme_key_release (key);
}
gpgme_op_keylist_end (ctx);
}
out:
gpgme_release (ctx);
return err;
}
int
main (int argc, char **argv)
{
int i;
if (argc < 2)
{
fprintf (stderr, "Usage: %s pattern...\n", argv[0]);
exit (1);
}
setlocale (LC_ALL, "");
gpgme_check_version (NULL);
gpgme_set_locale (NULL, LC_CTYPE, setlocale (LC_CTYPE, NULL));
#ifdef LC_MESSAGES
gpgme_set_locale (NULL, LC_MESSAGES, setlocale (LC_MESSAGES, NULL));
#endif
for (i = 0; i < argc; i++)
list_key_validity (argv[i]);
return 0;
}
/*
* Local variables:
* compile-command: "gcc -o list-key-validity list-key-validity.c `gpgme-config
--cflags --libs`"
* End:
*/
I get:
$ ./list-key-validity A6CC6651 D1458906
084B0E86A6CC6651 (pub) revoked = 0, expired = 1
892F1451D1458906 (pub) revoked = 1, expired = 0
892F1451D1458906 (sec) revoked = 0, expired = 0
Maybe I'm missing some points of the OpenPGP concept.
