Can I implement a one way hash
 

Hi,
I've created a password protected website using ASP for a project. However, for authentication, the username and passwords are passed as clear text parameters to the ASP. How can I implement a one way hash mechanism so that the database stores the hashed values of the password, and not the cleartext? I would appreciate examples and steps to implement this. The site is working perfectly with authentication. I just need to encrypt the passwords.

Also, how do I implement the go to loop? Im using VBScript as the language in the ASP pages....

Thanks.
