    gnupg_verify — Verifies a signed text

    Description

    gnupg_verify(
        resource $identifier,
        string $signed_text,
        string $signature,
        string &$plaintext = ?
    ): array|false

    Verifies the given signed_text and returns information about the signature.

    Parameters

    identifier

    The gnupg identifier, from a call to gnupg_init() or gnupg.

    signed_text

    The signed text.

    signature

    The signature. To verify a clearsigned text, set signature to false.

    plaintext

    The plain text. If this optional parameter is passed, it is filled with the plain text.

    Return Values

    On success, this function returns information about the signature. On failure, this function returns false.

    Examples

    Example #1 Procedural gnupg_verify() example

    <?php
    $plaintext     = "";
    $res = gnupg_init();
    // clearsigned
    $info = gnupg_verify($res,$signed_text,false,$plaintext);
    print_r($info);
    // detached signature
    $info = gnupg_verify($res,$signed_text,$signature);
    print_r($info);
    ?>

    Example #2 OO gnupg_verify() example

    <?php
    $plaintext     = "";
    $gpg = new gnupg();
    // clearsigned
    $info = $gpg->verify($signed_text,false,$plaintext);
    print_r($info);
    // detached signature
    $info = $gpg->verify($signed_text,$signature);
    print_r($info);
    ?>

    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"?
