Is there a guide for obtaining the value for slot0x0DKeyN? #8

The Citra wiki page on the topic has no advice about how to dump the keys themselves; just how to format 'aes_keys.txt' file.

I tried keys obtained through other methods, and I got a 'bad decrypt' error.

How did you get the appropriate keys?

openssl for unknown reasons throws a bad decrypt error even with the correct keys. Try running the curl verification steps outlined in the Readme to check if the file is fine. (For extra certainty, the md5sum of the resulting file should be 47a75886a0672b7f3d13603218b7b4bb).

For reference, the key itself is present in plaintext in the 3DS ARM9 bootrom, but I don't know its offset from the top off my head. (The Citra source suggests it's shortly after byte offset 55760.)

My checksum matches. Thank you for the help.
