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).

Notable Features
* Free and Open-Source software
* Unicode support
* Unobtrusive: easy to use, doesn't install any weird DLL files, doesn't write to the Windows registry, doesn't even write to your hard disk if you don't want it, can be uninstalled easily
* Uses up-to-date cryptography (AES, SHA-2) to generate random data for high-quality passwords
* Numerous password options for various purposes
* Generation of large amounts of passwords at once
* Generation of passphrases composed of words from a word list
* Pattern-based password generation (formatted passwords) provides nearly endless possibilities to customize passwords to the user's needs
* "Password hasher" functionality: Generate passwords based on a master password and a parameter string (e.g., the name of a website), similar to "Hashapass"
* Secure text encryption
* Multilingual support
* Runs on all Windows versions (32-bit and 64-bit; beginning with Windows 95 OEM Service Release 2)

2015-02-03 PWGen 2.5.3 released
NEW FEATURES:
- new character set "phoneticx", which allows for generating phonetic passwords consisting of mixed-case letters (in contrast to the "phonetic" set which generates phonetic passwords with lower-case letters exclusively), thus increasing the entropy by 1.0 bit per letter. Also note that the Translation Utility has been updated to version 1.1.2.
CHANGES & IMPROVEMENTS:
- when generating phonetic passwords with the options "Include at least one upper-case letter" and "Exclude ambiguous characters" activated, PWGen no longer checks which upper-case letters are not allowed and uses all 26 letters instead (reason: the "Exclude ..." option is not supposed to be effective for phonetic passwords)
- internal change: "Advanced password options" (which can be TRUE or FALSE) are stored as "bit masks" (integer values) instead of strings of 0s and 1s
