TrueCrypt - Disk Encryption Software for Windows, Mac OS X and Linux

Encrypt a disk space using AES, Serpent, Twofish, Cascades and their combination. After mounting the file, it appears as a drive and just work on it like a drive in your computer. It is not likely the file being decrpted even you lost your USB Device or your laptop or the file being accessible to your network administrator. Cool for your data privacy.

Not suitable for the scenario for multiple-write environment as it operates as follow:

• Single Read-Write mount only. If you want to modify on some secret files with a group of people, needs to wait until the file is unmount.
• Multiple Read mount only. If you mount it as Read-Write, the other people cannot mount even they want to read only.
