Wii Uses Elliptic Curve Cryptography For Saves

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).'"

HAHA, and your calling the OP an idiot. "you are completely within your rights to attempt to break that encryption"

no your not last i checked circumventing encryption was illegal in 1/2 a dozen countries.

why do you freaking nerds have to defend nintendo all the time? they aren't going to love you back you know.
