cryptlib/example.js

CryptLib uses AES 256 for encryption or decryption. This library can be used for encryption and decryption of strings using Node on iOS, Android and Windows

/*global require*/

var /* cryptLib = require('cryptlib'), // Use this require if you load module through npm */
    cryptLib = require('./dist/CryptLib.js'),
    plainText = 'This is the text to be encrypted',
    iv = cryptLib.generateRandomIV(16), //16 bytes = 128 bit
    key = cryptLib.getHashSha256('my secret key', 32), //32 bytes = 256 bits
    cypherText = cryptLib.encrypt(plainText, key, iv);

console.log('iv = %s', iv);
console.log('key = %s', key);
console.log('Cypher text = %s', cypherText);
console.log('Plain text = %s', cryptLib.decrypt(cypherText, key, iv));
