Hacking OTP Hash dumping with GodMode 9. How?

[einhuman197]

So the newest version advertises that I can dump my otp's hash. Because I dumped my otp 1 Year and 2 Months ago and I copied it like 15 times I would like to verify it. But when I make the "essential backup" it doesn't dump the hash. How can I backup that hash? Maybe @d0k3 can tell me. Or someone other.

you gotta be on 2.1.0

To verify my otp? I already have the otp I only want to verify it.

otp is getting locked by boot9. do a 2.1 ctrtransfer and then you can obtain the hash/otp

But why in the world is this feature included into GodMode9? Also arm9loaderhax saves the otp because it needs to decrypt the arm9loader partition.

So, ya know when you backup your nand with godmode9? That's pretty much useless without the otp.bin? You only get nand.bin.sha and nand.bin

Wtf are you talking about? You don't need otp.bin for your nand backup.

I also have seen this in the nand backup section and saw the new otp addition. I do not understand it either, but i did notice an essential.exefs in the virtual drive of the image after doing the nand backup. I don't know if that was there before or not. That probably contains whatever the new things is

Sorry, it said on 3ds.guide to back it up, along with the nand.bin

Okay I wrote with d0k3. He helped me. Thanks anyways.

People are confusing OTP and OTP hash I think.

Kernel9Loader does not clear the SHA_HASH register after use. As a result, the data stored here as K9L hands over to Kernel9 is the hash of OTP data used to seed the console-unique NAND keystore decryption key set on keyslot 0x11

Meaning we can get the OTP hash in an A9LH context simply by reading the SHA_HASH register.
