What are you not sure about? Bitcoin mining uses sha256, the asic hardware performs these hash calculations. You could just tell it to perform it on arbitrary inputs. [...]
Luckily you can't repurpose SHA-256 ASIC miners like that:
See they [ASIC Miners] don't even do that. They don't complete the double sha and don't return the hash at the end, only nonces that meet targets. So they really are useless.
(Quoted from ckolivas, developer and maintainer of cgminer so that guy knows his stuff)
Yeah I thought something like that would be the case. Good to know, thanks.
Good question why YOLOdice are using SHA-256 over SHA-512 though.
Suppose it is just an oversight that has historically been there but no one had noticed till now.
