Thanks!

I need something like this for a project I'm working on.

As part of a login reset I'm having the system email the user with a random generated string, and storing that string in the database. If the user enters the string from their email, they can reset the password.

This will help a lot with that, much more secure than the standard way of doing things.

Good written source, without errors and doing as supposed. Thank you.
Edit:

Just a tip.
Where "Letters" you can let the the source code user know that you mean Letter "UPPERCASE" and Letter "lowercase" combined.

For the rest I have a cool string generator now.
Regards.
