Secure Username and password verification using Javascript

[Wallykid]

I am wondering if there is a way to verify Username and password using Javascript securely. Javascript has client and server side script, and i know nothing about server side script. I know that for client side script, users can easily access the script by view source. Even if we try to hide the script by storing the script in a javascript.js file, they will still be able to download that file. So what is the normal way of doing it? Anyone?

My opinion is that JavaScript won't provide the security that you and your users deserve. I suggest using a server side language like PHP or ASP instead.

Thanks for all the answers. They do clear up my questions and also support my theory that javascript is not a secure way of doing password verification. Anyone knows what is the difference between server side script like PHP, ASP ?

There have been two or three threads on this subject lately. If you do a search, you may find some posts the would interest you. This link might also be of interest: http://pajhome.org.uk/crypt/md5/
