FreeOTFE4PDA is an open source, “on-the-fly” transparent disk encryption program for Windows PC and Windows Mobile Pocket PC devices. Using this software, you can create one or more “virtual disks” on your PC or PDA, anything written to which will be automatically, and securely, encrypted before being stored. Bpth the PC and Windows Mobile versions are inter-operatable: data encrypted on your computer can be read/written on your mobile device, and vice versa

Here are some of the main, common features of the PC and PDA versions of FreeOTFE:

+ Hash algorithms include: MD5, SHA-512, RIPEMD-160, Tiger and many more
+ Cyphers include AES (256 bit), Twofish (256 bit), Blowfish (448 bit), Serpent (256 bit) and many more
+ Cypher modes supported include CBC, LRW and XTS (including XTS-AES-128 and XTS-AES-256)
+ “Portable mode” included; FreeOTFE doesn’t need to be installed before it can be used
+ “Hidden” volumes may be concealed within other FreeOTFE volumes, providing “plausible deniability”.
+ FreeOTFE volumes have no “signature” to allow them to be identified.
+ Encrypted volumes can be either file or partition based.
+ Supports password salting (up to 512 bits), reducing the risks presented by dictionary attacks.
+ Allows users to backup and restore the critical areas of volume files.
+ Keyfile support included; store volumes and their associated metadata separately.
+ Volume file timestamps and attributes are reset after dismounting, increasing “plausible deniability”.
