FreeOTFE4PDA v3.05 (freeware)
Requirements: PocketPC 2003(SE), WM5, WM6
Overview: 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...!

Nice Release, +5 WRZ$ Reward. Category: Security.

Why would someone need this? Why would it be important that this provides the user with "plausible deniability" of files on their device? The only people who would need that, surely, are paedophiles hiding images, and criminals.

Well, how often do you read in the newspaper that yet another government official looses his pc or PDA with a lot of confidential data on it?
I often have confidential documents and files for my work stored on my PDA. They are in fact all located on a FreeOTFE drive, so nobody else can access them when I loose my PDA.
