- acqq 10y agoIf the hash is SHA256 they can, read your links.
- ikeboy 10y agoSorry, the second link has better info on exactly why it won't work directly.
- acqq 10y agoThanks. Yes, I agree completely, when it's "directly." The mining devices aren't designed specifically to crack the passwords, but the solutions have the raw processing power and use the same hash algorithm, it's just that somebody would have to adapt the chips for that given task, and for that he could keep most of what's already optimized, namely the fast SHA256 calculations in hardware. It won't be particularly hard to adapt some current solution, and the known speed benefit and power use would approximately remain.
- ikeboy 10y agoI think you'd need to design your own hardware, since the algorithm is hardcoded into these. And once you're doing that you'd lose the economy of scale that bitmain has.
