This open-source software enables creating on-the-fly encrypted virtual disks on a computer. All data written to these disks gets instant encryption for secure storage. The program is free to use and transparent with its encryption process.
FreeOTFE is easy to use and comes with a full wizard for creating new volumes. It offers a feature where data encrypted on your system can be read/written from your PDA, and vice versa. One of its strengths lies in its powerful support of numerous hash/encryption algorithms, giving it a higher level of flexibility than other OTFE systems, including commercial ones. It supports hash algorithms like SHA512, RIPEMD160, Tiger, and cyphers such as AES (256 bit), Twofish (256 bit), Blowfish (448 bit), Serpent (256 bit), among others.
The software operates on both PC and PDA platforms, and its compatibility with Linux (Cryptoloop "losetup", dm-crypt, and LUKS) is a great feature. Furthermore, the software has much more to offer, including hidden volumes for plausible deniability, file-based or partition-based encrypted volumes, and a modular design that enables 3rd party drivers to be created, incorporating new hash/cypher algorithms. The software also allows for keyfile support and the storage of volumes and associated metadata separately. Volume file timestamps and attributes are reset after dismounting to increase plausible deniability, and there are many other additional features worth exploring.
Overall, FreeOTFE is an exceptional software, and anyone looking for a reliable and flexible OTFE encryption system should look no further than this program.
