BFBOX Version 2.0 is a "secure data box" to store sensitive user data such as user names, passwords, lock combinations, account numbers, product keys, credit card numbers, PIN's and other identity numbers. User data is encrypted using the Blowfish algorithm with 448-bit keyword, then stored inside the BFBOX.EXE executable file itself. Decrypted user data is displayed to the monitor only. It is never written to disk. For security against keylogging, screen capture malware and phishing, install BFBOX on a computer that is never connected to the internet. BFBOX runs under Windows 2000, XP, or 32-bit Windows 7.

FMTQ Version 2.0 is a program that checks audio file extensions and formats.
