Small library for encryption via phpseclib

1. Install via composer

   composer require sivin/crypt

2. Register extension in config.neon:

   extensions: crypt: SiViN\Crypt\DI\CryptExtension

3. Create or use your key/s:

   /** @var Crypt */ private $crypt; public function __construct(Crypt $crypt) { $this->crypt = $crypt; } ... $keys = $this->crypt->createKeyPair() $privateKeyRaw = $keys['privateKeyRaw']; $publicKeyRaw = $keys['publicKeyRaw'];

4. Use your own key or define it in a config.local.neon:

   $crypt->setPublicKey($myPublicKeyForEncrypt); $crypt->setPrivateKey($myPrivateKeyForDecrypt); //if there is a private key with a password $crypt->setPrivateKeyPassword($myPivateKeyPasswordForDecrypt);

   or in a config.local.neon:

   crypt: publicKeyPath: publicKeyFile.pub #for encrypting privateKeyPath: privateKeyFile.key #for decrypting privateKeyPassword: 'PrivateKeyPassword' #optional

   If you only want to encrypt/decrypt, just define the encrypting/decrypting key

5. And finally?:

   $encryptedStr = $crypt->encryptRijndaelMessage($stringToEncode); //for transport $decryptedStr = $crypt->decryptRijndaelMessage($encryptedStr); $encryptedStr = $crypt->encryptRsa($stringToEncode); $decryptedStr = $crypt->decryptRsa($encryptedStr); $encryptedStr = $crypt->encryptRijndael($stringToEncode); $decryptedStr = $crypt->decryptRijndael($encryptedStr);
