jpwgen

jpwgen is a cool Java-based password generator that you can use as either a command line tool or as a library. It's pretty handy!

What Makes jpwgen Special?

This software has features similar to the well-known pwgen program. If you're curious, you can check out the *nix version of pwgen at pwgen. The main idea behind jpwgen is to create passwords that are easy enough to remember but still complex enough for real-life use.

Platform Independent and Flexible

Since jpwgen is built entirely in Java, it works on any platform! It even improves on pwgen by using regular expressions to check different password conditions. For example, it can see if a password starts with a symbol or digit, among other things.

Password Blacklists and Generators

This tool supports blacklists and various secure random generators. You can use it as an embedded library for generating passwords that meet specific policies or for suggesting passwords.

The Algorithm Behind Passwords

jpwgen uses a set of vowels and consonants combined using an iterative algorithm. It also incorporates diphthongs, which can represent either consonants or vowels. For instance, 'ei' is a vowel diphthong while '-th' represents consonants.

Unique Password Creation

You can choose from several algorithms for generating unique passwords. This makes sure your passwords are one-of-a-kind!

Built-in Filters

When you start jpwgen, it comes with two default filters. The first one is an empty blacklist filter that helps you filter out any forbidden passwords (like 'qwerty'). The second filter uses regular expressions to enforce common rules about symbols, digits, etc.
