jlasman said:I've taken the liberty of editing your post subject to "Do not allow easy passwords"; I hope I made the right decision.
Linux and Unix both already contain fairly good dictionaries which can be used for just this purpose. In fact if you add a user from the command line and use an easily-hackable password, your server will return a warning, though it will still let you use the password.
The only problem I see is a customer expectation issue; many clients will want to be able to use passwords they're comfortable with instead of passwords you're comfortable with.
Great idea, though.
