Hola, podrias usar md5 para ello, pero como Javascript no tiene una funcion nativa de md5, puedes copiar el codigo de esta pagina
, te dejo la funcion md5 y la utf8_encode ya que md5 requiere codificar en utf8.
Código Javascript
:
Ver originalfunction md5 (str) {
// Calculate the md5 hash of a string

// version: 1109.2015
