gnupg_verify — Verifies a signed text

说明

array gnupg_verify ( resource $identifier , string $signed_text , string $signature [, string &$plaintext ] )

Verifies the given signed_text and returns information about the signature.

参数

identifier: gnupg 标识符，由对 gnupg_init() 或 gnupg 的调用生成。
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.

返回值

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

范例

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));

}
