Re: Encrypt in Javascript and Decrypt in PHP????

Hey! There's no MD5 in Javascript which is why I post hte question in the first place. Now I lost 5 hours of my time working on writing this script. You're going to have to be careful because you had to make sure there is MD5 features in Javascript before posting a reply. I found a workaround to it. You have to manually create a MD5 algorithm in Javascript. I did the google search and got this, it is at http://www-adele.imag.fr/~donsez/cours/exemplescourstechnoweb/js_securehash/ . Pretty cool, isn't it!!!!! Take care, Scott "Scott Fletcher" <scott@abcoa.com> wrote in message news:20030110160708.59273.qmail@pb1.pair.com... > I'll look into this and try it out.
