The only hardware crypto blocks the Wii had were SHA and AES, there wasn't a hardware RSA block.
Which makes sense, it had to run both SHA and AES over large blocks of data; But RSA was only ever used on small amounts of data to verify tickets, and only when launching a new title.
I'm not sure what they licensed from RSA. The patents for RSA had already expired, so maybe the code?
- yuriks 2y agoThey probably meant RSA the company (https://en.wikipedia.org/wiki/RSA_Security https://en.wikipedia.org/wiki/RSA_Security), which was founded by the inventors of the algorithm, but has sold various other crypto devices and algorithms over the years, though I don't know if they ever sold hardware IP cores, and haven't been able to find anything about it. I feel like it's more likely they licensed patents or maybe code from them though.
