Introduction

• 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
• Cypher modes supported include XTS, LRW and CBC (including XTS-AES-128 and XTS-AES-256)
• "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!
• Security tokens/smartcards supported for extra (optional) security
• Operates under both PC (MS Windows 2000/XP) and PDA (Windows Mobile 2003/2005 and Windows Mobile 6) 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)
• Comprehensive documentation
• Naturally, fully supported by SecureTrayUtil.
• Plus more...!
