Password SafeThe security of Twofish in a password database
SupportPassword Safe is now an open source project. As of February 7, 2014, the latest Windows version is 3.33. A Linux version is currently in beta. To download the program, or for technical support, please visit its Sourceforge page.
Various third-party ports, clones, and readers are also available. I haven't looked at any of these programs, and can't vouch for their compatibility or their security.
With Password Safe, a free utility designed by Bruce Schneier, users can keep their passwords securely encrypted on their computers. A single Safe Combination--just one thing to remember--unlocks them all.
Password Safe protects passwords with the Twofish encryption algorithm, a fast, free alternative to DES. The program's security has been thoroughly verified by Counterpane Labs under the supervision of Bruce Schneier, author of Applied Cryptography and creator of the Twofish algorithm.
Password Safe features a simple, intuitive interface that lets users set up their password database in minutes. You can copy a password just by double-clicking, and paste it directly into your application. Best of all, Password Safe is completely free: no license requirements, shareware fees, or other strings attached.
