The Sudden Policy Change In Truecrypt Explained

X10 (186866) writes "I use Truecrypt, but recently someone pointed me to the SourceForge page of Truecrypt that says it's out of business. I found the message weird, but now there's an explanation: Truecrypt has received a letter from the NSA." Anyone with a firmer source (or who can debunk the claim), please chime in below; considering the fate of LavaBit, it sure sounds plausible. PCWorld lists some alternative software, for Windows users in particular, but do you believe that Microsoft's BitLocker is more secure?

      Could you clarify? Who is Alyssa Rowan to TrueCrypt? Sorry for my ignorance, I tried Googling a bit and just got links to this article.

      It's someone who has been active in the crypto/security community for awhile now. Personal details are pretty scarce (i.e. it could be a front for the NSA for all anyone knows), but the persona has been active in crypto. If you want something to Google on try "alyssa rowan cryptography".

      That's exactly what I thought first. But then it came to my mind that Bitlocker is much more secure than Truecrypt, because it has been developed and carefully audited by a corporation with a proven track record in cyber security. That fact makes it practically 100% certain that the developers of Truecrypt just thought "nah, fuck it, we now have Bitlocker, which uses military-grade encryption against all kinds of criminals and cyber-threads, and there are minor to medium potential problems with our code, so we just throw the towel and give up all the work on Truecrypt."

      That's obvious, right?

      Amen brother! I switched to Bitlocker a while ago and never even looked back at LUKS or TrueCrypt. The problem I had, though, was that I run only Linux on my machine. No worries. I installed VirtualBox, created a VM and installed Windows on it. That way I could make /home/lsllll as a private share available in the VM and have Bitlocker go at it. That is the ONLY reason why I run Windows. God praise the Bitlocker developers. They saved me from the NSA.

    this is actually a link to an interesting article, not goatse. it's an editorial about how the most recent full version of true crypt (7.1a) is still as secure as it was last week, and there's no reason to stop using it. It also says they (who?) are working on an open license fork that will be released on a future date.

    There is nothing I think worth adding to "Marlor's" post to Ars:

    I can't comprehend the conspiracy theories flying around about this.

    [TrueCyrpt] is a barely-maintained Open Source project (no updates in the past two years), with an outdated, messy code-base, serious build dependency problems, and lacking in full support for the newest Windows release. It likely only has a small development team - perhaps only one or two people.

    The developers are absurdly secretive, and when they do come out of hiding to make a statement, they are confrontational (take, for example, their response to Fedora's queries over the clause in their license that reserves the right to sue for copyright infringement).

    If this was any other project, we'd all just assume the developers had decided to call it a day. However, because of the nature of the software, everyone assumes security agencies or reptilians are involved.

    Maybe the developer was a security researcher who has decided to retire to a tropical island. Or maybe there were two developers, and they have had a dispute. Maybe the primary developer took a job offer at a security firm, with a clause prohibiting him from working on external projects. There are an almost infinite range of possibilities... assuming that the cause was the devious acts of state-sponsored actors is leaping to a pretty big conclusion.

    If I developed a piece of security software, and wanted to cease development, I'd make a similar statement.

    "Don't use this anymore. It's not maintained, and should therefore be considered insecure".

    Otherwise, if a vulnerability is discovered, everyone will scream: "Fix it now! Nobody told us to stop using it!"

    The simplest explanation is that the developers simply got tired of the project and decided to abandon it. It's been years since any update and it's certainly plausible that those developers remaining simply decided it wasn't worth it to keep the project alive when no one was maintaining it. .

    Ennead was 29 in 2005 (http://www.wolfmanzbytes.com/windows/70-truecrypt-encryption.html) and they obviously developed it on their freetime.

    Fast forward from that to today and you got couple of middle-aged devs, probably with more demading careers and perhaps even families and maybe with young kids.

    WARNING: Using TrueCrypt is notsecure as it may contain unfixed security issues

    But this raises many questions.

    (1) If Truecrypt were secure in the first place, a National Security Letter would have been of no use: the developers would be no more help de-crypting something than anyone else. So in the usual context, a NSL has no point whatever.

    (2) A demand for other records, say about the developers, would also not invalidate the CODE of Truecrypt in any way.

    So that only leaves a couple of possibilities as legitimate reason for a canary: (3) Possible coercion by the government to somehow weaken their crypto.

    (4) Discovery of some prior "backdoor" that had somehow been inserted in the past.

    (5) Maybe some of the developers wanted to remain strictly anonymous and so any overtures made by the government at all created panic.

    Since the people doing the security audit have announced that it will continue, if it turned out to be (4) it will be discovered soon. Which it seems to me leaves only (3) and (5) as any kind of government "threats" that make any sense.

    Any other ideas?

    I would guess that they were NSL'd for their signing keys; that would make it less secure in the future so the correct option is to burn the brand now. Reports said that both signing keys signed the new (crippled/canaried) executable, and that the keys had been re-uploaded with the same content on sourceforge. Their legit URL points to their sourceforge site. Instances of "U.S." in their source code were replaced with "United States".

    It looks to me like they went through a lot of trouble to burn the brand down before any damage could be done with the NSA's new-found signing keys. It's a very, very bad sign that this happened to TrueCrypt. Good on them for being brave enough to inform us, despite the real risks they faced in doing so. If this project is forked, we can only hope the new maintainers are brave enough to do the same when the NSA goes after them. It also raises the question: how much other infrastructure has been compromised while the maintainers have stood silently by?

    Not only that, but the trolling poster also made the assumption that you're not important, which is bullshit for the simple reason that we're ALL important to the people who love and care about us. We're important to someone - I'm important to my wife for example, and soon I'll be important to my newborn. Just because I'm not a politician or celebrity and hence known to thousands/millions of people doesn't mean I'm not important. It's all about spheres of influence - some are larger than others, but they still all matter.

    If the trolling poster honestly believes with such passion that you aren't important, it stands to reason they probably don't feel they are important either. If they can't find at least one person in their life who considers them important in some way... then I find that truly sad for the AC.

    TrueCrypt never claimed to protect you from a compromised system. The point of it was offline security. Once unmounted the contents of an encrypted container are inaccessible to anyone without the key.

    Once you understand what TrueCrypt is for you can see why it is so valuable.
