I am using gnupg for digital sign file in php. It was working fine before. Suddenly I am getting this error:

PHP Fatal error: Uncaught exception 'Exception' with message 'get_key failed'

putenv("GNUPGHOME=/tmp");
$publicKey = file_get_contents("./media/public.key");

$gpg = new gnupg();
$gpg->seterrormode(gnupg::ERROR_EXCEPTION);
$info = $gpg->import($publicKey);
$gpg->addsignkey($info['fingerprint'], DIGITAL_FILE_PASS);
$signed = $gpg->sign($data_to_sign);

What could be the reason?

Information:

$info variable looks like this:

Array
(
[imported] => 0
[unchanged] => 2
[newuserids] => 0
[newsubkeys] => 0
[secretimported] => 0
[secretunchanged] => 0
[newsignatures] => 0
[skippedkeys] => 0
[fingerprint] => 622FC43AB6E1FC175C08E9C0048EAEBF6E607FA3
)

  • Can you also provide the public key that cannot be imported? This is important for reproducing the problem. Otherwise, at least post an anonymized output of `gpg --list-packets public.key`. – Jens Erat Oct 04 '15 at 20:03

  • Check if the web user has permissions for ALL the gpg files in $GNUPGHOME. If you run gpg2 commands on those files as a different user, the permissions are likely changed. – site Sep 07 '18 at 03:21

Although your code is correct but I don't know why file_get_contents is not working correctly in your code, Kindly give it a try using cURL:

This function is an alternative to file_get_contents.

function url_get_contents ($Url) {
    if (!function_exists('curl_init')){ 
        die('CURL is not installed!');
    }
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $Url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    $output = curl_exec($ch);
    curl_close($ch);
    return $output;
}

    Somehow, now it's working in my old code. But, I will try it in your way if I'll face same issue again. Thanks a lot! – RNK Nov 30 '15 at 16:52

Add below code to line 2 in your code.

$publicKey = file_get_contents(getenv('GNUPGHOME')."./media/public.key");
