Our web host recently updated the version of gnupg on our server to 2.0.13.
without telling us of course!! This broke GNuPG class at the list keys function. and caused big problems for us.
gnupg 2.0.13 outputs a different format to older versions.
we had to hurriedly write a funtion which converts the output from the new gnups into the old format for listkeys() to read
This worked and the code is below. I am sure it can be tidied up we wrote it in a big hurry.
Two functions are shown the new gpg_format() and listkeys() with a slight code mod to read from gpg_format()
//convert between old and new gpgp output may 2010
function gpg_format($input){
$n1 = $n2 = 0;
foreach($input as $tak => $tav){
$fds = explode(':', $tav);
if (count($fds) <= 3) continue;
if($fds[0] == 'pub' || $fds[0] == 'sec' ) {
$ta1[$n1] = "$fds[0]:$fds[1]:$fds[2]:$fds[3]:$fds[4]:$fds[5]:$fds[6]:$fds[7]:$fds[8]:";//$fds[9]:";
$ta2[$n1] = $tav;
$n1++;
}elseif($fds[0] == 'uid'){
$ta3[$n2] = "$fds[9]:$fds[7]:";
$n2++;
}else{
}
//}
}
unset($fds);
if($n2){//if uid rows present
foreach($ta1 as $tk2 => $tv2){
$contents[$tk2] = $tv2.$ta3[$tk2];
}
}else{
$contents = $ta2;
}
return $contents;
}
function ListKeys($KeyKind = 'public')
{
// validate the KeyKind
$KeyKind = strtolower(substr($KeyKind, 0, 3));
if (($KeyKind != 'pub') && ($KeyKind != 'sec')) {
$this->error = 'The Key kind must be public or secret';
return false;

$returned_keys = array();
// the keys are \n separated
$contents = explode("\n", $contents);
//print_r($contents);
$contents2 = $this-> gpg_format($contents);//change format for updated gpg on unix 2.0.0.13 quadrahosting
