TL;DR: Last Pass is broken. All passwords at the time of the breach were taken. They also got internal secrets from a laptop and can now probably throw computational power at anything they want to decrypt.
Switch. Do not use. Change everything you have if you were using it. Treat everything as breached.
Password Safe and the Twofish encryption algorithm it uses were originally developed and released to the public by Bruce Schneier and Counterpane Labs.
Password Safe is now an open source project hosted at sourceforge.net. The latest program updates, documentation, and news can be located at http://pwsafe.org.
