PasswordGen is a program that generates cryptographically secure
passwords. The length of the password can be specified, as well as
the characters that are used. The program outputs the password in
plain text and in hashed forms for various common use cases.
Usage
PasswordGen [<size> [<alphabet>]]
- size
- Specifies the length of the password to generate.
