Wii Uses Elliptic Curve Cryptography For Saves

Posted by Zonk on from the advanced-tech dept.

An anonymous reader writes "A user at the Nintendo-Scene forums just posted a lengthy post about his discovery that the Wii savegame files are signed and encrypted with NIST B 233 bit elliptic curve cryptography. Could this be the first step for a Wii softmod the homebrew community have waited for? From the post: 'It appears a Wii savegame file ends with a certificate chain. The certificates contains a public keypair (the one that is being "certified") and a signature (another number pair) from the signing entity. The number pairs are stored as a compound 60 bit data (first 30 bytes for the first number, and the next 30 bytes for the second). Hence, the first and middle byte is always 00 or 01 for keys, and 00 for signatures. One can check that the keys are indeed NIST B 233 keys using openssls EC_KEY_check_key function (code forthcoming).'"

    Such hate creates oppression and violence. I recommend you show love by letting others live. I'm and Xian, and don't speak of others in such a manner.

      It's not a question of letting others live. Many creationists want it taught as science, which it most clearly is not.
