I just bought WD My Passport Essential SE 1TB USB 3.0 drive, but before I put my precious files there, I need to make decision what kind of protection to use. There are 2 obvious choices: the WD’s disk password and the TrueCrypt software.
I’m fan of TrueCrypt, which is by far the best software to protect data. It is very well documented, free (as in free beer), there are sources available, doesn’t have any government backdoors inside, has carefully selected algorithms. In short - very well implemented piece of cryptography.
I would like to know in more details how does WD’s HDD password work. Is there any doument that outlines its internals? How is data protected – is it encrypted in some way? If so, then by which algorithm? And how long is the actual master key used to encrypt data?
Cryptographic solutions are only trustworthy if they are publicly known, not obscured, so anyone brave can try to bypass them and fail. I don’t need, or want, to crack the drive’s encryption, I just need to know if I can trust it. And you may call me paranoid
Thanks in advance.
