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
  • 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.
  • Plus more...!
