This "on-the-fly" (OTFE) transparent disk encryption program is free and open source.

Manufacturer’s Description

FreeOTFE is a free, open source, "on-the-fly" (OTFE) transparent disk encryption program. Using this software, you can create one or more "virtual disks" on your PC - anything written to which will be automatically, and securely, encrypted before being stored. Features include: - Source code freely available. - Easy to use; full wizard included for creating new volumes. - Data encrypted on your PC can be read/written on your PDA, and vice versa. - Powerful: Supports numerous hash/encryption algorithms, and provides a greater level of flexibility than a number of other (including commercial!) OTFE systems. - 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. - "Portable mode" included; FreeOTFE doesn't need to be installed before it can be used - making it ideal for carrying your data securely on USB drives! - Operates under both PC (MS Windows 2000/XP) and PDA (Windows Mobile 2003/2005) platforms. - Linux compatibility (Cryptoloop "losetup", dm-crypt and LUKS supported). - "Hidden" volumes may be concealed within other FreeOTFE volumes, providing "plausible deniability". - FreeOTFE volumes have no "signature" to allow them to be identified as such. - Encrypted volumes can be either file or partition based. - Modular design allowing 3rd party drivers to be created, incorporating new hash/cypher algorithms. - 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. - Uses per-sector IVs, including support for ESSIV. - Volume file timestamps and attributes are reset after dismounting, increasing "plausible deniability". - Supports volumes files up to 2^63 bytes (8388608 TB). - Plus more...!
