PHP Privacy is an implementation of the OpenPGP standard in PHP language. It implements RFC4880, RFC6637, parts of RFC4880bis.

Requirement

• PHP 8.1.x or later,
• phpseclib library provides cryptography algorithms,
• (optional) PHPUnit to run tests,

Features

• Support data signing & encryption.
• Support key management: key generation, key reading, key decryption.
• Support public-key algorithms: RSA, DSA, ElGamal, ECDSA, EdDSA and ECDH.
• Support symmetric ciphers: TripleDES, IDEA, CAST5, Blowfish, Twofish, AES, Camellia.
• Support hash algorithms: MD5, SHA-1, RIPEMD-160, SHA-256, SHA-384, SHA-512, SHA-224.
• Support compression algorithms: Zip, Zlib, BZip2.
• Support ECC curves: secP256k1, secP384r1, secP521r1, brainpoolP256r1, brainpoolP384r1, brainpoolP512r1, curve25519, ed25519, prime256v1.

Installation

Via Composer

$ composer require php-privacy/openpgp

or just add it to your composer.json file directly.

{
    "require": {
        "php-privacy/openpgp": "*"
    }
}

Basic usage of PHP Privacy

Sign and verify cleartext message

<?php declare(strict_types=1);

require_once 'vendor/autoload.php';

use OpenPGP\OpenPGP;

$armoredPublicKey = '-----BEGIN PGP PUBLIC KEY BLOCK-----';
$armoredPrivateKey = '-----BEGIN PGP PRIVATE KEY BLOCK-----';
$passphrase = 'Your passphrase';

$publicKey = OpenPGP::readPublicKey($armoredPublicKey);
$privateKey = OpenPGP::decryptPrivateKey($armoredPrivateKey, $passphrase);
$cleartextMessage = OpenPGP::createCleartextMessage('Hello, PHP Privacy!');
$signedMessage = $cleartextMessage->sign([$privateKey]);
$verifications = $signedMessage->verify([$publicKey]);
