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).'"

    Is the question why your personal device keeps secrets from you. It's your savegames. You should be able to modify them as you wish. Yet another case of a company treating customers like criminals.

    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.

    >I recommend you show love by letting others live.

    it would be nice if your god would do the same.

    I don't care about whether you use swear words or not, but if you believe that the world was created by a powerful being that discriminates between the "worthiness" of people on the basis of their sex, sexuality, skin colour, not chopping off foreskin, sex before marriage, etc etc or any other personal matter then you are being far more insulting than if you had simply said "fuck off you cunt".

    creationists spread many very offensive ideas themselves, even if they use "pollite" words to phrase it.

    but while christian and other religious prejudices are annoyingly stupid, I don't believe people have a right to not be offended.

    Creationism is the amusing theory that the stories of a nomadic desert people hold more truth than scientific discoveries made 4000 years later. Creationists aren't that much of a nuisance though, since they do not have any more computers than the Israelites did.
