In 3.56 Sony fixed the metldr exploit (hardware) by wrapping its security around bootldr (hardware)
In 3.60 Sony fixed the ECDSA Algorithm, making the variable which was supposed to be randomly generated work as intended
What does this mean?
The ability to sign files (PUP, PKG, etc...) is lost because of the change of private key (not hardcoded) and the fix of ECDSA prevents us form getting the key again.
TO CLARIFY:
The recent exploit of bootldr (lv0) (hardware, Sony's Final Defense) allow the ability to modify PUPs 3.56+ which is why we are getting 4.21, 4.25, 4.30
BUT since the private key used in the OFW has been changed and is unknown, 3.60+ IS NOT POSSIBLE (Rogero 4.21 and E3 4.30 are still using 3.55 private key which is why you need 3.55)
ECDSA WILL NOT BE CRACKED. If it is, GLOBAL security will be compromised, as many other databases, websites, etc. are using ECDSA
If you need proof or further reading, google ECDSA.

ReAct PSN can be used to get valid licenses for content. Yes, PSN access on 4.30CFW is not DNS or Proxy.

Well put. A retard (such as myself LOL) can understand this. Very easy to read and comprehend.

It's even longer than that. It's estimated it would take your average super computer 0.65 BILLION years.
pow(2,12
/ (15 * pow(2,40)) / 3600 / 24 / 365.25 / 1e9 / 1e90.6537992112229596
However, going off Moore's law and assuming we continue to double computer speed every year, then in roughly 60 years, it should only take 1.13 years to break. But, given that half of us will probably be dead by then and at not playing ps3, i'd say it's reasonable safe to say, you're fucked if you try crack it ha
