    It was fine (except the past time, just a "d" added?), but very well understandable.
    I don't know how better he could have worded it.

    http://3dbrew.org/wiki/Title_metadata has some stuff but it appears to be a mix of RSA and SHA1 hashing as a base for some signatures (not sure what) and word is some AES is used elsewhere. If the other nintendo handhelds ( http://dsibrew.org/wiki/Main_Page , http://nocash.emubase.de/gbatek.htm#dscartridgesencryptionfirmware ) and recent consoles ( http://wiibrew.org/wiki/Wii_Security ) are anything to go by (and what data is available points to Nintendo not doing a ground up rewrite/redesign) though the rest can be a somewhat varied mix of stuff.

    3DS Titles (Retail & 3DSWare) (not DS/DSi/DSiWare) are encrypted with AES-CTR (sometimes just xorpads)
    The data then hashed with various Hash algorithms (SHA-512, SHA-256, SHA-1, HMAC-SHA-1, HMAC-SHA-256) and signed with RSA-2048 or RSA-4096.

    This doesn't help us a bit with "hacking".
