I am creating a web application that will securely connect to a server and update the user's password. I have been looking at using MD5 to create the hash to send to the server but I want to make the app as secure as possible.
Part of the task will be to create a URL that takes a MD5 hash of the time stamp as part of the URL and when the user attempts to access the script, it will verify that the time stamp hash is the same as the one in the database which is logged by the update password script.
The big question is there a perl mod that will setup assist with the hash creation and verification?
