FreeOTFE is a free, open source, “on-the-fly” transparent disk encryption program for PDAs . Using this software, you can create one or more “virtual disks” on your PC/PDA. These disks operate exactly like a normal disk, with the exception that anything written to one of them is transparently, and securely, encrypted before being stored on your computer’s hard drive.

Features:

* Source code freely available
* Easy to use; full wizard included for creating new volumes
* Both PC and PDA versions are available; data encrypted on your PC can be read/written on your PDA, and vice versa
* No need to install it; making it ideal for use on USB memory drives, etc
* Optional support for smartcards and security tokens
* It’s powerful: Supporting numerous hash (including SHA-512, RIPEMD-160, Tiger) and encryption algorithms (including AES, Twofish and Serpent) in several modes (CBC, LRW and XTS) – providing a much greater level of flexibility than a number of other (including commercial!) OTFE systems
* Encrypted volumes may either be file, partition, or even disk based
