  Because javascript runs in the browser on the client side, you
cannot absolutely rely on it to do input validation -- and under
NO circumstances should you rely on it for *authentication*!

Hi Johnny,

You can try using javascript functions to validate input 
(i.e. user passwords ) in a text field based on your password 
complexity requirements and  put the page on your internal web server.

Hello Nic,

Thanks for the reply. I was looking for a tool for users to check 
whether the passwords they choose meet the organization's 
policy. Not 
a tool to test the strength of the existing passwords. Most 
likely a 
web portal for them to enter the "potential" password, and 
the portal 
will determine whether it meets the standards.

You cannot check the quality of "Unix/Linux" passwords as it's a 
one-way encryption so it must be done at the time the user 
(or admin) 
sets the password. With PAM based authentication on *nix there are 
ways of enforcing stronger passwords standards than the default.
As far as Windows goes I have no experience with security.

Hello all,

I was wondering if your organization deploys any password quality 
checking tool to help users select policy-compliant 
passwords? Be it 
web-based or client based. I am thinking what type of 
requirements 
do you use to select such tools, and what are the 
examples out there?

My thoughts:
1) It should not store the user's passwords (be it pass or fail)
2) It should be able to handle complexity rules (or align with 
Windows GPO)
3) It should also work with Unix/Linux passwords

Thanks,
JW
