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).
