ninty-233

ninty-233 is a library for ECC operations using sect233r1 / NIST B-233, the curve used in the iQue Player and Nintendo Wii.

It can be used for ECDH (used to create some encryption keys on the iQue Player) and ECDSA signing/verification (used to sign game saves on both consoles and to sign recrypt.sys on the iQue Player).

Arbitrary-precision arithmetic is done using the public domain C++ Big Integer Library by Matt McCutchen.

SHA1 implementation is from the public domain WjCryptLib by WaterJuice.
