TrueCrypt - Free Open-Source On-The-Fly Disk Encryption Software for Windows 7/Vista/XP, Mac OS X and Linux. How To Make Encrypted Folders Others Can’t View with Truecrypt 7. Truecrypt is a practical implementation of paranoia for your PC, and Version 7 has an even bigger stash of goodies to ease your worries, along with better performance.
We’ll use that app today to illustrate how to create an encrypted folder that others can’t explore. Before we begin though, a couple of references. Mark has talked about Truecrypt a couple of versions back, and he also wrote a great article specifically about using Truecrypt on a USB stick. Saikat gave a broader outline on how to hide folders. What Is It? So is Truecrypt all about hiding folders? Truecrypt is also cross-platform, as well as being open source freeware to encrypt folders.
Why Do I Need It? Unfortunately we live in a world where people don’t behave the way you might wish they did. Even if you never do anything you would like to keep private, if you have an online life of any sort, your identity and your information are valuable items, and you need to look after them. View Forum - General. Accidently restored incorrect header backup! Thanks Dan!
This pretty much answers my question - I'm screwed. The only backup of the (correct) header for this drive is on a disk that was recently nuked with DBAN before selling it as part of complete machine, so recovery is not an option. ;( My parting question would have to be: Why is it even possible to restore a backup header file to "any" volume, regardless of whether or not that backup originated from that volume and thus destroying it's header and any hope of recovery in the process should it be wrong? Is there no way some sort of check could be in place to determine whether or not this is the likely valid header for this volume, and if not prompt the user to override if they're certain?
Plea to TC Developers: Please consider a backup header validity check as a possible option to protect idiot users like myself from themselves. ;) Even if a quick volume SIZE comparison could be made, it would help prevent a scenario like this. Anyway, thanks to all who responded in this thread! GMail Drive Shell Extension and TC? Has anyone tried the GMail Drive Shell Extension and TC together to see if they work?
I might have a crack at this on the weekend but I am curious if anyone has tried it out. For those not familiar with the GMail Drive Shell Extension it is a small application that 'maps' a GMail account to a virtual HD, allowing you to store and retrieve files online through the windows explorer - it looks like a hard drive to your pc. I am expecting that it wont work due to the required headers TC needs and I expect the vitrual drive wont have.
Still worth a try..... The Frog. Cascading Aes-Twofish-Serphent question. Let's see.
If you read the docs you will find that each cipher in the cascade uses its own key, independent of the other keys. For three cascades of 256-bit keys that makes a total of 768 bits of key material. The effective key length might be somewhat less according to things I have read, but it's not the case that the three cascades only add 2 bits of key length. As far as your "3 lots of 4-bit only give you 5-bit", I think you were trying to say that the key lengths don't add - but they do. Each cipher uses a separate key. Your logic about bits adding up is not correct. To use your example of 4 bits, if there was a cascade each cipher would have its own 4 bit key so there would be 12 bits total. In the case of a 256 bit key, the additional 512 bits adds about 10^154 values. Password strength will 43 characters or more give 256 bits entropy? I keep reading that 40 or 43 characters will produce 256 bits entropy.
So I am assuming that any password 43 characters or longer that contains a mix of upper and lower case letters, has some numerals and special characters, contains no sequences of three letters (case insensitive) or numerals, contains no words in any language, would be very difficult to hack. What if the password is not truly random? Run a command after mounting encrypted volume (windows) Hi All, Question: Is it possible for TrueCrypt to issue a command on the successful mounting of an encrypted volume (windows)?
My situation: I have an encrypt partition setup to auto mount on login (TrueCrypt asks for the password on login). If the partition is mounted successfully, I would like TrueCrypt to issue a command to run a vbscript that will ask me if I want to run my backup software and backup my machine to this encrypted volume (what the volume is for). I will proved an answer and the vbscript will act accordingly. At this point it's all a matter of invoking the script (or other commands depending) at the correct time. Thanks, Reactor89.
