FreeOTFE 4.00

FreeOTFE is a free, open source, “on-the-fly” transparent disk encryption program for PCs and PDAs (Windows Mobile 2003/2005).

Using this software, you can create one or more “virtual disks” on your PC/PDA - anything written to these disks 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
* 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
* Decryption software available to improve transparency, and allow even the most junior software engineer to prove data is being encrypted correctly
* 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)
* Naturally, fully supported by SecureTrayUtil.

What’s New in version 4.00:

* Added support for 64 bit versions of MS Windows
* Added support for PKCS#11 (Cryptoki) security tokens/smartcards
* Significantly improved partition selection system
* Further commandline options
* Various other enhancements!
