They're your most realistic option right now. They are actively developing it and added things like newer algorithms (e.g. SHA2). There's CipherSched but that is basically a completely new program/rewrite which is very far from done. However, I don't agree with VeraCrypts choices. They've changed several things that make mounting slow (0,5s -> 10s), which is annoying, especially if you mistype the password. Providing…

This is an odd conclusion to come to. Are there a lot of users of True/Veracrypt that don't understand this? I guess I just don't see my grandparents using either of these packages, and I can't imagine a lot of "normal" users "trying out" a new encryption program.

10 seconds is ridiculous, especially if you know what you're doing and use strong passphrases.

The passphrase to one of my TrueCrypt volumes is around 30 characters long. It's not completely random, so let's say it only has 2 bits of entropy per character. That's 60 bits total. A brute-force attack would take an average of 2^59 guesses before it succeeds.

At 10 seconds per guess, we're looking at approximately 180 billion years to crack my passphrase. Even if you devoted a million computers to the job (as an extremely well-funded adversary might do), it would still take 180,000 years.

If you weakened the PBKDF to take 1 second instead, it would take 18,000 years to crack my relatively weak passphrase using a million computers. That's still long enough that I don't care at all. Moreover, if I were really paranoid, I can easily bring it back to the 180,000-year mark (or more) by adding a few more characters to my passphrase, which would only take another second to type. So why wait 10 seconds?

It is available the version 7.1a, but the TrueCrypt development has stopped (for now). An alternative solution is VeraCrypt (build over Truecrypt 7.1a): https://veracrypt.codeplex.com/ VeraCrypt says to add extra security features (ex. TrueCrypt uses PBKDF2-RIPEMD160 with 1000 iterations whereas in VeraCrypt we use 327661): https://veracrypt.codeplex.com/discussions/569777#PostConten... Do you think VeraCrypt is an v…

zuluCrypt[1] is another option if you are on linux.

Its GPL licensed and exists in a lot of distribution's repositories(Will appear in debian and ubuntu repositories shortly)

It supports TrueCrypt volumes,VeraCrypt volumes and LUKS volumes.

Just because a person is older than you doesn't mean they're either stupid or completely non-technical. Plenty of older people started using computer in the middle of the sixties. So what if we started with card punch machines, tape readers, and mainframes? Just exactly what do you mean by "normal?" How much computer exposure does it take before one loses that quality and becomes, well, "you?" There are lots of grand…

I understand that there's a prejudice against older people regarding technical ability, but the parent poster didn't actually say anything regarding old people in general, just about his/her grandparents specifically.

You can bruteforce much faster on GPU.

E.g. 20*10^9 ripe160 hashes per second on 8x AMD R9 290X (price is around $3000): https://hashcat.net/oclhashcat/

60 bits are not secure against attacker with medium budget.

Why would someone want to use Veracrypt but not have the increased security? Why not just use Truecrypt?

Some years before oclHashCat support, I buil a gpu cracker for truecrypt volume TrueCrack (https://code.google.com/p/truecrack/) . To be honest oclHashCat has better performance. Now the board of the oclHashCat tests ( AMD R9 290X ) costs about 300 euro (not $3000).

Under Linux, what is the advantage of TrueCrypt/zuluCrypt over plain old LUKS? (which is automatically set up on any modern Linux Distro installation)

> Disclaimer: this site is not affiliated with, nor is it the official site of TrueCrypt AFAIK there are several forks out there. But who is behind them? Can they be trusted? BTW, for those looking for the code, this is the only reliable host for the Truecrypt source code: https://github.com/AuditProject/truecrypt-verified-mirror

We don't even know who was behind TrueCrypt itself. How could that be trusted? Because it was open source and people could and have reviewed the code.

There is no advantage. Choosing TrueCraft is a choice to use software with more questionable origins.
