    XXTEA for NodeJS

    Introduction

    XXTEA is a fast and secure encryption algorithm. This is a XXTEA library for NodeJS.

    It is different from the original XXTEA encryption algorithm. It encrypts and decrypts Uint8Array instead of uint32[], and the key is also Uint8Array. If you want to encrypt String, you can use xxtea.toBytes(str) to convert String to Uint8Array, when you decrypt Uint8Array, you can use xxtea.toString(bytes) to convert the result to String. Conversion between string and Uint8Array is using UTF8 encoding.

    Usage

    var XXTea = require('./XXTea');
    var btoa = require('btoa');
    var atob = require('atob');
     
    var passPhrase = 'SomeCrazyPassword!#00';
    var message = 'Some secert message';
    console.log("original message: " + message);
     
    //construct
    var tea = XXTea();
     
    //encrypt the message into a byte array
    var encryptedBytes = tea.encrypt(tea.toBytes(message), tea.toBytes(passPhrase));
     
    //convert to a string and base64 encode it
    var encryptedString = btoa(tea.byteArrayToString(encryptedBytes));
    console.log("encrypted message: " + encryptedString);
     
    //decode the base64 string and convert back from string to a byte array
    var encryptedBytes2 = tea.stringToByteArray(atob(encryptedString));
     
    //decrypt
    var decryptedBytes = tea.decrypt(encryptedBytes2, tea.toBytes(passPhrase));
     
    //convert the decrypted bytes into a string
    var decryptedString = tea.byteArrayToString(decryptedBytes);
     
    console.log("decrypted message: " + decryptedString);
