Correct me if I'm wrong, but this can't happen with their ASICs. Password cracking works backwards from hashing, right?
The general idea of mining is to run thru a SHA256 hash twice. They take x and turn it into y like this:
y = (SHA256 (SHA-256 (x)))
This is assuming their ASIC does both steps at once. Their ASIC may only do one hash at a time, but it would still look like this:
z = (SHA256 (x))
y = (SHA256 (z))
For password cracking, you would need some way to go from an already encrypted password that's only gone through one SHA256 encryption (z, in the example above), and un-encrypt it into x. It was my impression that this sort of password cracking works backwards from bitmining. The ASIC could be use to encrypt passwords, but there would be no use for something that fast.
Bitmining: x --> SHA256 --> z --> SHA256 --> y
Password: x --> SHA256 --> z
Cracking: z --> CRACK --> x
Does that make sense? Anyone more knowledgeable care to point out any blatantly obvious holes in my reasoning?

Someone more knowledgeable than I am will probably chime in here, but they don't crack passwords like this. For cracking, you have the hash of the password. You then take your password guess, hash it, then compare that hash to the value you have. Rinse and repeat several trillion times.

I'm not too up on my cryptology and password hacking, so I would not be surprised if you are right!
