Hi chaps.

I've just been taking a little time to look at the software known as Truecrypt in a little bit more depth.

I was just reading an article which makes for some uncomfortable reading.

In short, the article states that

QUOTE
"No one knows who wrote TrueCrypt.

No one knows who maintains TC.

Moderators on the TC forum ban users who ask questions. They also claim to be open source, but do not maintain public CVS/SVN repositories and do not issue change logs. They ban folks from the forums who ask for change logs or old source code. They also silently change binaries (md5 hashes change) with no explanation… zero. The Trademark is held by a man in the Czech Republic ((REGISTRANT) Tesarik, David INDIVIDUAL CZECH REPUBLIC Taussigova 1170/5 Praha CZECH REPUBLIC 18200.) Domains are registered private by proxy. Some folks claim it has a backdoor. Who Knows?"


I have used it myself previously, but I have become a bit more wary of it, with the discovery that there is software available which can detect the existence of truecrypt partitions.

It operates on the basis of identifying them using 4 criteria ;

1. No File Header.
2. (File size / 512) = 1
3. Successful X2 and Arithmetic Mean tests on certain bytes.
4. File size greater than 15 MB.

Anyone have any thoughts on either the integrity of the (presumed unknown) authors, or of the integrity of the executable binaries which are made available?

I think encryption is illegal in some countries especially in the US, so the authors could be rightly nervous about revealing their identities

as for 'fit for purpose' ..in the uk a least

Where a person given a section 49 notice knowingly fails to make the disclosure required they commit an offence. If the disclosure required is necessary in the interests of national security they may be convicted on indictment to a maximum of 5 years imprisonment or in any other case 2 years. On summary conviction they may be liable to a maximum six-month term of imprisonment or a fine not exceeding the statutory maximum or both.

depending on what your encrypting you could end up with a longer sentence for withholding the key than you would get for the encrypted data, its not really possible to hide truecrypt from someone who's looking for it, a better solution would be to write your own encryption tool then it wouldn't have a known signature than can be detected by a scan, not as hard as it sounds ..you could use MS batch code or just about any other lang that's capable of reading a single byte from a file

Mmmm yes, I am not too familiar with US law, so I couldn't comment on the legality of encryption methods over there.

There are several appealing features of Truecrypt, namely that it supports full disk encryption, and supposedly undetectable hidden truecrypt filesystems, and it is portable across a variety of platforms.

(I don't actually have anything to hide, I simply hold an amatuer interest in the field. I think my truecrypt volume contains a few philosophy ebooks, and some football stuff, I don't ever use it really)

It just strikes me as a highly irregular mode of operation on behalf of the maintainers of truecrypt. Making alterations to executable binaries without detailing exactly what changes have been made is, in my opinion, highly irregular in the field of 'open' development.

As you fine well know Shadester, it certainly couldnt be classed as `open source` if the source code is not publicly available,
is it possible that the devs just cannot be bothered highlighting changes in the code to n00bs with 101 q`s when all could be revealed by an examination of the code?

Philosophy books? is that what they are called nowadays? ah must be well behind on the modern jargon! rofl.gif

Hi, i have used this prog for years especially the plausible deniability, i use this as people may know/find out you have an encrypted partition but they can not see the hidden partition or know you have one.

a friend of mine who studyed encryption and security (amongst other things) at uni is happy with it and the availability of the code. He did say that some of the questions asked on the forum would make him fuck people off, a bit like someone on here asking if you need lights to grow. As to a backdoor, after a conversation with the same guy (most of which i have no idea wtf he was on about) i am happy to use it. Just make sure you use a decent password using caps, lower case, numbers,punctuation and special symbols. an easy way to remember a long password is by using the first letter from the words in a memorable song or piece of writing, if it contains no numbers replace a letter or throw 1 in. My password is 37 characters long and is the only password i never forget!

PS if you use a song try not to hum/sing it to yourself when people are watching you by the computer.

You should ask them then, cos ye certainly fit that description yerself.
The only 'code' you've ever examined is the writing on the menu at the cantonese takeaway when yer pished. tongue.gif
