CAST IN THE NAME OF GOD. YE NOT GUILTY. ^ Apparently an RSA-OAEP constant in a version of Nintendo 3DS game card anti-piracy that was never used.

Someone liked The Big O
One of the 128bit key scrambling functions used in the 3DS (IIRC) was ((X ^ Y) + "任天堂株式会社".encode("utf-16")) ROL 42 IIRC. Yes that's UTF-16LE with BOM. Added 128-bitwise.

Or was that DSi, I forget.

it was the dsi. the 3ds engine had the same dumb partial key overwrite bug though but I don't remember if the secret was similar as well

Still better than the PS Vita F00D key

Was that the one that was just a single byte repeated 16 times?

Please correct me if I'm wrong, but as long as that's only ONE of them and there are other functions in play as well, that's... not terrible? It's a nice Nothing Up My Sleeve number. It's certainly amusing.

This was a key obfuscation function. The security of that is predicated on 1) the constant/construction not being guessable, and 2) the output not being extractable. "Nintendo Co Ltd" is not great for 1, and implementing the partial key overwrite bug is not great for 2.
