How do I obtain an HMAC key, keygen_erk, and keygen_iv?

Post by pcmantinker » Thu Aug 20, 2015 4:09 am

I've been researching how to generate resource URLs for trophies, but I haven't been able to find good information on how to obtain an HMAC key, keygen_erk, and keygen_iv value from np_trophy_util.prx. If it requires a jailbroken PS3, I'm out of luck for the time being. I am not asking anyone to provide dumps of their keys as I'm sure that's not permitted. The code I have been looking into getting working is on the psdevwiki: http://www.psdevwiki.com/ps3/Trophy_files#Tools

I understand that some people pay for this type of thing, but I was curious if I could get these keys myself without too intensive of effort? I'm more of a web developer than a console hacker, but this resource url method is the most accurate method of obtaining trophy data from Sony.

I managed to research some more of what I need to get the HMAC key, erk, and iv from np_trophy_util.sprx. I found https://github.com/wargio/ps3tools and got it compiled and running with MinGW but I'm not sure how to use the leaked PS3 keys with the compiled applications. It looks like after I decrypt the np_trophy_util.sprx module, I can obtain the HMAC key, erk, and iv for using with the Python script. Does anyone know how to install the keys used with these tools? I'm not asking for the keys, but just how to set them up.
