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).
