TrueCrypt 4.3 Released

RedBear writes "A new update to the best open source transparent encryption software has been released. TrueCrypt is (the only?) open source encryption software capable of creating and mounting encrypted virtual disk images that can then be worked with transparently like any other storage drive, with data encrypted and decrypted in real-time. These virtual disks can be created as files, or entire partitions or physical drives can be encrypted and mounted transparently. Sadly there is still no Linux GUI or Mac OS X port in sight. If you are one of the thronging hordes who have been patiently awaiting ubiquitous multi-platform encryption, please consider donating time or money to the cause, and add your voice to the forum." From the site:"Among the new features [are] full compatibility with 32-bit and 64-bit Windows Vista, support for devices and file systems that use a sector size other than 512 bytes (such as new hard drives, USB flash drives, DVD-RAM, MP3 players, etc.), auto-dismount when a host device (e.g., a USB flash drive) is inadvertently removed, and many more." Read on for more features of TrueCrypt and cached versions of all the links above.
Also including features like plausible deniability, steganographically hidden volumes, unidentifiable partition headers, traveler mode, and your choice of the strongest available encryption algorithms up to and including multi-algorithm cascades. TrueCrypt is practically the Holy Grail for advocates of free ubiquitous encryption. Now, if only it were platform independent.

To reduce load on their servers here are some Coralized versions of all the links:

Re:Algorithm Cascades == BAD?

[Copid]

I am, actually, a mathematician (though not a cryptographer), but I could've sworn that doing "cascades" like this is actually a bad idea, mathematically? I seem to remember times where it can actually *weaken* the overall level of protection if you just do it carelessly without regard to the mathematics.

My understanding is that in the general case, there's no truly compelling reason to believe that cascades are either stronger or weaker. I believe that there are special cases with certain algorithms, but the people who maintain TrueCrypt are aware of them. I don't recall the exact details, but it's discussed fairly frequently on sci.crypt.

Re:No OS X Port?

Blew mod points to respond to this.

Disk Utility, the graphical application, is not open source. diskutil and hdiutil, the command-line programs it is a front-end for, are open source. I don't know whether the DiskImages framework (which hdiutil could be considered a front-end for) is open source, though. (my guess is "yes")
