Frequently Asked Questions

Note: The latest version of the VeraCrypt FAQ is available at

https://veracrypt.codeplex.com/wikipage?title=FAQ.

Can TrueCrypt and VeraCrypt be running on the same machine?

Yes. There are no conflicts between TrueCrypt and VeraCrypt, thus they can be installed and used

on the same machine.

Can I use my TrueCrypt volumes in VeraCrypt?

Yes. Starting from version 1.0f, VeraCrypt supports mounting TrueCrypt volumes.

Can I convert my TrueCrypt volumes to VeraCrypt format?

Yes. Starting from version 1.0f, VeraCrypt offers the possibility to convert TrueCrypt containers and

non-system partitions to VeraCrypt format. This can achieved using the "Change Volume

Password" or "Set Header Key Derivation Algorithm" actions. Just check the "TrueCrypt Mode",

enter you TrueCrypt password and perform the operation. After that, you volume will have the

VeraCrypt format.

Before doing the conversion, it is advised to backup the volume header using TrueCrypt. You can

delete this backup safely once the conversion is done and after checking that the converted volume

is mounted properly by VeraCrypt.

What's the difference between TrueCrypt and VeraCrypt?

VeraCrypt adds enhanced security to the algorithms used for system and partitions encryption

making it immune to new developments in brute-force attacks.

It also solves many vulnerabilities and security issues found in TrueCrypt. The following post

describes parts of the major enhancements and corrections done in version 1.0e:

https://veracrypt.codeplex.com/discussions/569777#PostContent_1313325

As an example, when the system partition is encrypted, TrueCrypt uses PBKDF2-RIPEMD160 with

1000 iterations whereas in VeraCrypt we use 327661. And for standard containers and other

partitions, TrueCrypt uses at most 2000 iterations but VeraCrypt uses 655331 for RIPEMD160 and

500000 iterations for SHA-2 and Whirlpool.

This enhanced security adds some delay only to the opening of encrypted partitions without any

performance impact to the application use phase. This is acceptable to the legitimate owner but it

makes it much harder for an attacker to gain access to the encrypted data.

I forgot my password – is there any way (‘backdoor’) to recover the files from my VeraCrypt

volume?

We have not implemented any 'backdoor' in VeraCrypt (and will never implement any even if asked

to do so by a government agency), because it would defeat the purpose of the software. VeraCrypt

does not allow decryption of data without knowing the correct password or key. We cannot recover

your data because we do not know and cannot determine the password you chose or the key you

generated using VeraCrypt. The only way to recover your files is to try to "crack" the password or

the key, but it could take thousands or millions of years (depending on the length and quality of the

password or keyfiles, on the software/hardware performance, algorithms, and other factors). Back

in 2010, there was news about the FBI failing to decrypt a TrueCrypt volume after a year of trying.

While we can't verify if this is true or just a "psy-op" stunt, in VeraCrypt we have increased the

security of the key derivation to a level where any brute-force of the password is virtually

impossible, provided that all security requirements are respected.
