FreeOTFE4PDA is a free, open source, "on-the-fly" (OTFE) transparent disk encryption program. Using this software, you can create one or more "virtual memory cards" on your PDA - 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 - 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 - "Hidden" volumes may be concealed within other FreeOTFE volumes, providing "plausible deniability" - Encrypted volumes have no "signature" to allow them to be identified as such - 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. - 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" - Plus more...! A PC version is also available, allowing data encrypted on your PC to be read/written on your PDA, and vice versa  [edit]  Less
