Bitcoin FPGA for PW hacking


Recommended Posts

I've sen these FPGA or ASICs used to mine bitcoins. FPGA are FAST, and stacking them kinda makes sense.

Now bitcoin is just hash work, so pondering using these 'boxes' to crack PWs and such.

Easy, hard, near impossible, or pointless?

Theoretically, yes, but the downfall is that these devices have code on them that's specifically for bitcoin mining. You would have to modify or write your own code for other uses, and that is no simple task for FPGAs, since everything is done in digital logic rather than a programming language like C, and their performance relies on how efficiently you write your logic.

The reason it works for bitcoin is that everything is the same encryption, the same length, etc. You hardly find that with passwords, so for max performance, you need to write different logic sets for different types of passwords and encryption methods
