can you show me how i would use Crypt::GeneratePassword?

See the documentation on CPAN for examples.

Also, if it is a module that needs to be installed, then my ISP will not allow me to do this

The module appears to be pure Perl, so you can simply copy the .pm files to your script or library directory, or you can include the text of the .pm files into your scripts as long as you preserve the "package" declarations.
