RSA and Bootsector decryption?
Where is that RSA info from? Is it possible to decrypt the RSA block on DSi, or on 3DS, or both? Any hints how to do that? Are DSi and 3DS using the same RSA key?
The notice about keyX being same as for "Tad" sounds good... until one figures out that the "srl extract" utility contains only a normal "key" (not a keyX/Y pair), so decrypting isn't possible even when knowing keyY. Of course, whomever has found the normal key, should be also able to find the keyX/Y values, but I've no idea how that could be done (it will certainly not work with cooking coach which has all keyslots erased, so it might require main ram hacks in worst case).
The part about "binblk->binblocksize" is the actual binary size is confusing. If binblk->binblocksize is known, then what is binblocksize in the formula? Or is that a typo, and it means same as binblk->binblocksize?Nocash 14:27, 27 March 2015 (CET)
- 1/3) See last page edit.
- 2) One can easily obtain the keyX^keyY key with F_XY_reverse(<any normalkey>) from that tool, but of course that's rather pointless without a keyX/keyY to XOR with that. Besides ramhaxx, the only other way to obtain the keyX/keyY for that yourself is to just get it from the 3DS DSi-key-stash @ 0x01FFD000(essentially *all* DSi keys are stored in there + TWL_FIRM Process9).

Bootloader Error Photos
Here are some shots of my DSi with what I think is a bootloader error. --The2Banned2One 17:25, 24 November 2010 (CET)
