How safe is TrueCrypt? Is it worth it to use it?

post #1 of 37
Thread Starter 
My father just bought a Corsair Flash Voyager GT 64GB Flash Drive to transport documents from his job, however, he's scared that he might lose his pen drive and someone gets access to his sensitive information, and uses it for dangerous purposes.

I heard TrueCrypt is a good encryption tool but, let's be honest: how safe is it?

He's not an average joe: he NEEDS the highest protection he can get for his data.

So let's be honest: how crackable is TrueCrypt? is there a way to make a TrueCrypt partition as safe as possible?

Is there any better encryption solution than TrueCrypt? And if TrueCrypt is the best, what kind of settings would make that partition almost uncrackable, even with the fastest supercomputers?

Maybe I'm asking just way too much, but I hope that you can understand that it's really important for him, and our family.

Your help will be higly appreciated

Thanks!

TrueCrypt is pretty good but you have to understand that ANYTHING can and always will be crackable. It just depends on how determined the person is at getting at the data and how much time he is willing to pour into it.


There is no "uncrackable"

There never will be.

If the drive stores anything remotely dangerous, then it should not be on there. Instead he should be using a USB drive that uses hardware based encryption, such as from the excellent Kingston Datatraveler Vault Privacy edition drives.

Still, software encryption is a MUST, that's why he didn't get a hardware-based encrypted drive... he still can return his Flash Voyager though, and change it for another model if he pleases.

Based on this criteria, what would be the best settings to make a TrueCrypt volume as safe as possible? we're talking about paranoid levels of security. I need something that takes YEARS if not more to crack...

Any ideas?

The idea is that, if he changed his flash voyager for a 64GB hardware-encrypted drive, and it fell into the wrong hands, the hardware based encryption stops those guys from accessing our data, and if they manage to bypass it, then, they access the drive just to find a bunch of silly files, in one of them the TrueCrypt volume would be hidden, and then they'd have to crack that volume, that's why it needs to be as strong as possible so it takes as much time as possible to be cracked.

Thus the hardware approach. Enter the password incorrectly a certain amount of times, and all the data gets deleted. You can certainly use Truecrypt, and it is effective, but not entirely trusted by everyone.

I work in an IT department that bans every unencrypted thumb drive across the organization; for us it is hardware based Kingston-like drives, or nothing.

And, is there any 32-64GB hardware-based flash drive that can do the job with the highest level of security?

There is no "uncrackable"

There never will be.
Quantum Encryption is an uncrackable way of transferring data.

If a man-in-the-middle looks at the data, it changes the data. Heisenberg uncertainty principle FTW.

let's just say that your dad is a greater security threat than truecrypt

if the password is long enough (at least 15 chars), and you properly generate the seed or whatever its called by moving your mouse, you will be safe

Ok then, I'll tell my dad about those drives.

However, the TrueCrypt encryption can NOT be left aside, as I stated in a previous post above, the idea is to use hardware protection first, and if it fails, then we'll have to rely on the TrueCrypt volume ok?

so we're back to the main question: in order to make thos volume as uncrackable and safe as possible, which settings do I have to use?

I have TrueCrypt open atm and already clicked on the partition creation wizard. I'm creating an encrypted file container with the option "standard TrueCrypt volume" (for now). Now, here's where things get interesting: Encryption Algorithm and Hash Algorith:
What do I choose here? I guess these are the options that can make the volume stronger, I don't know. What options do I choose from here to achieve what I need?
