HMAC Key

[FeitX]

Does anybody know what HMAC key does the Vita use? Is it the same as this?:

Code: Select all

As what Proxima had posted, or does the Vita use multiple HMAC keys for a lot of it's signature checks?

That key is only used in calculating the download http url for a game or app title update. It does not relate to any other feature or HMAC in the Vita.

Thought so too, but I had to make sure it does . Another question, are HMAC-keys just sitting inside modules? For I would like to know, I might do a bruteforce attack on finding one, that is if the previous algorithm provided still matches what the Vita uses.
