Exception when trying to use 64 digit key

[lasergoat]

FIrst off, thank you for making this repo!

node -v
v10.16.0

Using this code:

    const { Encryptor } = require("node-laravel-encryptor");
    const key = Encryptor.generateRandomKey(64, "base64");

    let encryptor = new Encryptor({
      key: key,
      key_length: 64
    });

    const result = encryptor.encryptSync("TEXTTOENCRYPT");
    console.log(result);

Exception is thrown:

     EncryptorError: Invalid key length
      at Function.throwError (node_modules/node-laravel-encryptor/dist/base_encryptor.js:256:15)
      at Encryptor.createCipher (node_modules/node-laravel-encryptor/dist/base_encryptor.js:144:28)
      at Encryptor.encryptItSync (node_modules/node-laravel-encryptor/dist/base_encryptor.js:35:29)
      at Encryptor.encryptSync (node_modules/node-laravel-encryptor/dist/Encryptor.js:21:50)

Yet, if I make a key of 32 and don't pass a key_length into the Encryptor constructor, it works. It's like the cipher algorithm isn't being set properly when the key is 64 digits.

When I use a 32 bit Key, it encrypts, but I am unable to make the encryptor instance in laravel:

    const originalPassword = "98b29b3b";

    const { Encryptor } = require("node-laravel-encryptor");
    const key = Encryptor.generateRandomKey(32);

    // copy this key to paste into laravel
    console.log("key:", key.toString("base64"));

    let encryptor = new Encryptor({
      key
    });

    const result = encryptor.encryptSync(originalPassword);
    console.log("base_encryptor.js:", result);

Now, take that key, and the encryption and use in artisan tinker for decryption:

// run php artisan tinker

$newEncrypter = new \Illuminate\Encryption\Encrypter( base64_decode('SrA+WaJ9CZilLJ51WWdQl/nor/6xMJ779yhi4JK43bk='), 'AES-128-CBC' );

// ERROR: RuntimeException with message 'The only supported ciphers are AES-128-CBC and AES-256-CBC with the correct key lengths.'

Hi.

Sorry for the delay answering , right now I'm not able to dig into it but I'll look this issue more carefully when I finish to settle down.

I just published an update.

Now options.key_length should be 128 or 256 to reflect what Laravel is ussing, aes-128-cbc or aes-256-cbc

generateRandomKey too:

const key = Encryptor.generateRandomKey();
const key = Encryptor.generateRandomKey(128);

Thanks for the advise and let me know if you have any problem.
