推荐答案

请参阅此URL，它对您非常有帮助.下载示例并尝试.

See this URL it is very help full to you. Download example and try it.

https://github.com/singpolyma/openpgp-php

或者尝试一下:-

您可以在URL上方下载 lib/openpgp.php 和 lib/openpgp_crypt_rsa.php 文件.

You can download lib/openpgp.php and lib/openpgp_crypt_rsa.php files in above the URL.

示例/keygen.php

<?php

require dirname(__FILE__).'/../lib/openpgp.php';
require dirname(__FILE__).'/../lib/openpgp_crypt_rsa.php';

$rsa = new Crypt_RSA();
$k = $rsa->createKey(512);
$rsa->loadKey($k['privatekey']);

$nkey = new OpenPGP_SecretKeyPacket(array(
   'n' => $rsa->modulus->toBytes(),
   'e' => $rsa->publicExponent->toBytes(),
   'd' => $rsa->exponent->toBytes(),
   'p' => $rsa->primes[1]->toBytes(),
   'q' => $rsa->primes[2]->toBytes(),
   'u' => $rsa->coefficients[2]->toBytes()
));

$uid = new OpenPGP_UserIDPacket('Test <[e-mail]>');

$wkey = new OpenPGP_Crypt_RSA($nkey);
$m = $wkey->sign_key_userid(array($nkey, $uid));

print $m->to_bytes();

示例/sign.php

<?php

require dirname(__FILE__).'/../lib/openpgp.php';
require dirname(__FILE__).'/../lib/openpgp_crypt_rsa.php';

/* Parse secret key from STDIN, the key must not be password protected */
$wkey = OpenPGP_Message::parse(file_get_contents('php://stdin'));
$wkey = $wkey[0];

/* Create a new literal data packet */
$data = new OpenPGP_LiteralDataPacket('This is text.', array('format' => 'u', 'filename' => 'stuff.txt'));

/* Create a signer from the key */
$sign = new OpenPGP_Crypt_RSA($wkey);

/* The message is the signed data packet */
$m = $sign->sign($data);

/* Output the raw message bytes to STDOUT */
echo $m->to_bytes();

?>

examples/verify.php

<?php

require dirname(__FILE__).'/../lib/openpgp.php';
require dirname(__FILE__).'/../lib/openpgp_crypt_rsa.php';

/* Parse public key from STDIN */
$wkey = OpenPGP_Message::parse(file_get_contents('php://stdin'));
$wkey = $wkey[0];

/* Parse signed message from file named "t" */
$m = OpenPGP_Message::parse(file_get_contents('t'));

/* Create a verifier for the key */
$verify = new OpenPGP_Crypt_RSA($wkey);

/* Dump verification information to STDOUT */
var_dump($verify->verify($m));

?>
