And to re-state really not taking credit for others work.. I just used all their tools and put it into 1 big "folder" for all of you to use. Hope this helps someone.
Edit #1: Edited license.txt and then I decrypted and encrypted lv0. without any changes (just testing the private keys) and it worked fine on my ps3.

Those are CORE OS files. You could get a sony sdk and program your own lv0, etc. and use it to make a cfw. as long as you can sign it with private keys it will run on the system.
fw yes..but not a cfw..if you think you get it then try it..and tell us if you get luck or not..

I may be mistaken but these are all the public keys, the private key which is protected by the ECDSA Algo is the one that is needed to create 3.56+ CFW and retail signed package files. This is old and is the reason why there is 4.xx CFWs BUT good job on doing the work.
Yes, But this could lead to something, So some how there could be a way to JB 4.xx without having to be on CFW Or 3.55.

I just tested on my 4.11 OFW and it runs fine.. Now I'm not trying to make a cfw/jb without proper ppc/ sony sdk knowledge but I edited the license.txt and encrypted then decrypted lv0 (no changes made) and repacked back to a pup. Loaded fine and works properly..

There are private keys in my download :p 4.40 and 4.41 and btw all the ecdsa is a digital signature to validate a file. It's just a hash. Plus I just tested and it works fine.

But that is the point, they are only able to be installed on 3.55 because the ECDSA Algo is not active on 3.55. Anything above 3.56, you'd need to be able to exploit the ECDSA and turn it back off or get the private key.
Sadly, I just don't see either happening but who knows. :/

Wait, huh? It worked on 4.11 OFW, what does that mean? You just repacked it as a PoC right, no debug options added? Simple OFW.
