    More precisions: -the written keys are random -they are written to keyslots 0xC and 0xD, the keyslots where the TSEC writes the real keys when it is satisfied -the function writing the fake keys is also called at each panic

    BTW, Nintendo is a troll: the very first thing the TSEC secureboot FW does is writing a key to the SE... but not any key you would want!

    To all pk1decryptor users: pk1decryptor is dead. It cannot decrypt the 7.0.0 package1 and never will be able to. Now the TSEC FW bypasses the SMMU (!!!)

    Woops! :P It looks like whatever engineer wrote this altered his message a bit since it first appeared in 0.996.070 Vita's secure kernel xD

    Also, here is the documentation of the secret TSEC FW I wrote a few days after. It describes the checks it is doing, and how it interacts with the outside world generally.

    Here is the tool I developed just after having successfully defeated the 6.2.0 protections with the SMMU trick. Pretty straightforward, it decrypts package1, and also gets you the TSEC root key, the TSEC device key, and the SBK as a bonus.

    Since there is no good reason not to make that stuff public, I'm releasing my 6.2.0 work/research from last November.

    The PS Vita master key is the scream Sony's security team is having when the cryptosystem is broken.
