You can see who made the signature by checking its fingerprint:

<?php
$res
= gnupg_init();
$info = gnupg_verify($res,$signed_text,$signature);
if(
$info !== false){
$fingerprint = $info['fingerprint'];
var_dump(gnupg_keyinfo($res, $fingerprint));
}

Where can I see description of result array?

I've got

Array
(
[0] => Array
(
[fingerprint] => 9BF78012F700B345827346E1EFA3026F01404358
[validity] => 4
[timestamp] => 1643100153
[status] => 0
[summary] => 3
)

)

But what does "status" mean? What is "validity"? What is "summary"?
