This is a simple package to generate (pseudo) random strings of specified length
separated into "blocks" of specified blockLength
s by specified separator
characters. This makes this package suitable for generating license or product or serial keys.
The similar looking characters (and numbers) I, 1, 0 and O are always left out of the generated strings to avoid confusion.
Note that the generated keys are just random strings and there's no provision to check their validity cryptographically.
