Bytessence PasswordManager
Bytessence PasswordManager is a free / open source personal information management tool, created for storing data like logins and passwords for different websites. While many internet services use such logins, the quantity of passwords people need to remember grows dramatically, reaching a point where they will use universal passwords or they will write them inside simple text files, making them a potential victim of data theft.
BPM was designed to be light, small and easy to use. It features active protection capabilities like a configurable boss key (hides BPM from the screen completely or restores it), automatic clipboard clearing (after a number of seconds the clipboard is cleared to get rid of any sensitive information), automatic close of open containers (useful in case you leave your PC unprotected) and automatic backup when saving files.
BPM can also be extended with plugins in the form of tools (virtual keyboard to avoid your keystrokes to be intercepted by hardware keyloggers, password analyzer and generator), importers and exporters. Best of all, BPM is open source so you can have a look under the hood and even help fix bugs or send suggestions for future versions.

Frequently asked questions
A: In order to properly secure the data inside the containers, BPM employs one of the strongest cryptographic algorithms available, AES-256 (also known as Rijndael, a symmetric-key encryption standard adopted by the U.S. government). Regarding the key generation algorithm, SHA-256 is used.
