This open-source program offers free transparent disk encryption that creates encrypted virtual memory cards on PDAs. All data written on them is automatically secured before storage.
One of the most significant benefits of FreeOTFE4PDA is that the software's source code is freely available. The software is also easy to use, and comes with a full wizard included that lets you create new volumes with ease.
FreeOTFE4PDA is incredibly powerful, supporting numerous hash and encryption algorithms, which provides a greater level of flexibility than many commercial OTFE systems available today. Some of the hash algorithms included in the software are MD5, SHA512, RIPEMD160, Tiger, and many more. FreeOTFE4PDA also supports a variety of cyphers, including AES (256 bit), Twofish (256 bit), Blowfish (448 bit), Serpent (256 bit), and many others.
The software provides a feature known as "hidden volumes," which lets users conceal FreeOTFE volumes within other FreeOTFE volumes, allowing for plausible deniability. Additionally, the encrypted volumes have no signatures, making it challenging to identify them as such.
FreeOTFE4PDA has a modular design, enabling third-party drivers to be created, incorporating new hash/cypher algorithms. It also supports password salting up to 512 bits, reducing the risks presented by dictionary attacks. The software includes keyfile support, allowing for volumes and their associated metadata to be stored separately.
FreeOTFE4PDA uses per-sector IVs, including support for ESSIV, and volume file timestamps and attributes are reset after dismounting, increasing plausible deniability further. A PC version is also available, allowing for encrypted data on your PC to be read and written to a PDA, and vice versa.
Overall, FreeOTFE4PDA is a powerful, flexible, and easy-to-use encryption solution that provides users with complete control over their data's security. With its many features and options, FreeOTFE4PDA is a reliable and effective choice for anyone looking for top-tier encryption software.
Version 5.21: Added Russian translation
