Simple String Encryption & Decryption with Node.js

encrypt_decrypt.js

function encrypt(text){
  var cipher = crypto.createCipher('aes-256-cbc','d6F3Efeq')
  var crypted = cipher.update(text,'utf8','hex')
  crypted += cipher.final('hex');
  return crypted;
}

function decrypt(text){
  var decipher = crypto.createDecipher('aes-256-cbc','d6F3Efeq')
  var dec = decipher.update(text,'hex','utf8')
  dec += decipher.final('utf8');
  return dec;
}

var hw = encrypt("hello world")
decrypt(hw)

// feel free to change >> d6F3Efeq
// To test just copy + paste the above inside the node shell
// TIP: always encrypt IDs before sending via HTTP
