gnupg_verify()

(PECL gnupg >= 0.1)

Verifies a signed text

说明

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

Verifies the given$signed_textand 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));
}
