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()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

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));
}
