PWGen is a password generator capable of creating large amounts of cryptographically-secure passwords or passphrases consisting of words from a word list. It uses a "random pool" technique to generate random data based on user inputs (keystrokes, mouse handling) and volatile system parameters. PWGen provides lots of options to customize passwords to the usersТ various needs. Additionally, it offers strong text encryption and the creation of random data files (e.g., key files).

2013-12-14 PWGen 2.4.0 released
The main feature of version 2.4.0 is the new "MP Password Generator" which allows generating passwords reproducibly based on a secret master password and a parameter string. This "password hasher" functionality is similar to the website Hashapass. The new "deterministic random generator" is related to this feature, as it enables the user to make password generation in PWGen (almost) completely reproducible; it can be activated in the MP Password Generator dialog (click on the new "magic hat" button in the toolbar)
