HalitePHP项目中libsodium封装
Halite 是PHP项目中一个简单的libsodium封装包。Halite提供高级的加密接口,依靠其所有潜在的密码操作libsodium。
Halite 基本 API:

示例1:加密解密消息
首先,生成一个key
<?php use ParagonIE\Halite\KeyFactory; $encKey = KeyFactory::generateEncryptionKey(); KeyFactory::save($encKey, '/path/outside/webroot/encryption.key');
然后,加密解密消息
<?php use ParagonIE\Halite\HiddenString; use ParagonIE\Halite\KeyFactory; use ParagonIE\Halite\Symmetric\Crypto as Symmetric; $encryptionKey = KeyFactory::loadEncryptionKey('/path/outside/webroot/encryption.key'); $message = new HiddenString('This is a confidential message for your eyes only.'); $ciphertext = Symmetric::encrypt($message, $encryptionKey); $decrypted = Symmetric::decrypt($ciphertext, $encryptionKey); var_dump($decrypted === $message); // bool(true)
示例2:用password-derived key 加密消息
<?php use ParagonIE\Halite\HiddenString; use ParagonIE\Halite\KeyFactory; use ParagonIE\Halite\Symmetric\Crypto as Symmetric; $passwd = new HiddenString('correct horse battery staple'); // Use random_bytes(16); to generate the salt: $salt = "\xdd\x7b\x1e\x38\x75\x9f\x72\x86\x0a\xe9\xc8\x58\xf6\x16\x0d\x3b"; $encryptionKey = KeyFactory::deriveEncryptionKey($passwd, $salt); $message = new HiddenString('This is a confidential message for your eyes only.'); $ciphertext = Symmetric::encrypt($message, $encryptionKey); echo $ciphertext, "\n";
