With this software, you can create one or more "virtual disks" on your PC/PDA. These disks operate exactly like a normal disk, with the exception that anything written to one of them is transparently, and securely, encrypted before being stored on your computer's hard drive.


  • Highly portable - Offers a portable mode, eliminating the need to install to the computer, there is also FreeOTFE Explorer; a system which allows FreeOTFE volumes to be accessed without installing software, and on computers where no administrator rights are available.
  • Easy to use - A full wizard is included for creating new volumes.
  • PC and PDA versions available. Encrypted data on your PC can be read/written from your PDA and vice versa.
  • Support for encryped Linux volumes (Cryptoloop "losetup," dm-crypt, and LUKS).
  • Available in multiple languages.
  • Optional support for smartcards and security tokens.
  • Powerful - Supporting numerous hash (including SHA-512, RIPEMD-320, Tiger) and encryption algorithms (Including AES, Twofish, and Serpent) in several modes (CBC, LRW, AND XTS), providing a much greater level of flexibility than a number of other OTFE systems.
  • Encrypted volumes can be file, partition, or disk based.

    Needed a portable encryption program and possibility to make encrypted volumes. This seemed like a good solution until i found out i cant use it on my computers (W7 and W8.1). Or any other pc i have acces to since they are all (W7 or W8) and the system need's signed drivers to install the drivers. Plz sign your Cryptography Programs Drivers and i will change it to 4/5 stars for all the options it seems to have. Best Regards, Darkyere
