I can save you from reading the rest of the comments and say that nobody knows. It's the same theories about being raided by the FBI and some still believe that it's secure to use.
This is the fork of Truecrypt plans on having active development after the TrueCrypt audit is complete. https://ciphershed.org/
There are two promising projects building on TrueCrypt code, though I wouldn't trust them without looking at the diffs manually. That said I did quickly glance over VeraCrypt's changes and it seems that the majority of the patches are related to fixing the problems uncovered in the TC security audit.
The current version of TrueCrypt is compromised by its authors but the previous version 7.1a is thought to be good although with a few weaknesses. See here for more details. TrueCrypt remains very interesting because of its cross-platform nature. Not only does it run on multiple systems, the volumes are largely portable between them.
Someone else has already mentioned the ciphershed project whose aim is initially to make an easy to build copy of TrueCrypt with known weak points cleaned up.
It says right on the website that: (Please note: currently unmaintained, which might have security implications)
I would much rather go with https://ciphershed.org/ since they are working with the 7.1a code and trying to make it better.
The official TrueCrypt project was shut down by it's developers, likely for the same reasons the Lavabit admin shut their site down. The last stable version of TrueCrypt was audited, and most of the security holes that were found were fixed in the TrueCrypt forks, VeraCrypt, and CypherShed.
Stay tuned to the VeraCrypt and CipherShed projects for TrueCrypt's successors.
Both are based on the TrueCrypt code base, but VeraCrypt is making changes based on what its maintainers believe is necessary to keep the software up-to-date as far as security technologies are concerned.
Until then...
Linux? LUKS
Windows? DoxBox
Mac OS X? No idea
Yes, you can find them here. But please, bear in mind that these binaries shouldn't be used in production or for securing critical data, they've been released only for testing. So if you're planning to use them, be careful.
Hmm, this looks promising. How does this compare to the upcoming CipherShed, another TC fork?
I just tried installing them both, and CipherShed refuses to co-exist with TrueCrypt while VeraCrypt works just fine.
Truecrypt is being re-made/forked. It has multiple forks out using the second to last release as a base due to the breaking changes in the newest and last release that effectively turned off the crypto for new data written to disk.
The new fork everybody seems to be getting behind lives at https://ciphershed.org/
you would trust hardware encryption on where ever the drive is made?
there are now open source versions of truecrypt you can use.
https://ciphershed.org/ under developement but
you can compile it yourself from the source.
veracrypt is pretty popular from what I've seen. There is also Ciphershed but that one is currently just starting up so there are only alpha builds.
