I am sure Sony has incorporated ways to prevent this long, LONG ago. Most likely, you would send encrypted packets, which would in turn get re-encrypted along the way, obfuscating the data. Or, the packets will use a random key/hash to encrypt the data which alone would make this impossible without knowing the algorithm used to generate the key/hash. Or it could always be done with certs, who knows, I haven't really paid any attention to this part of the PS3. One thing I can say is that there is no way this will work the way you have presented.

Edit: By the way, CFW users have no right being on PSN; some of us DO enjoy a cheat free online environment. CFW ruins this experience, PSN and CFW should never be allowed.

If that's true, then like you said, it's impossible to do it without knowing the algorithm
Good to see someone who knows what I mean.

If you send the already encrypted data, PSN will decrypt it, not the PS3 only.
Just like it does on 4.11
************* [ - Post Merged - ] *************
Also the reason that Yet another bypass 1.6 works on 4.00, is because the encryption and decryption method is still the same.

I have to disagree on that one. PSN on 3.55 = online cheating and a lot of legit players don't want that.
As much as I hate games such as CoD and BF, I don't think people who like it should have their game ruined by cheaters.

Anyway, as it was said, the PS3 sends console-specific info, which means even if said method worked, you'd need to sniff the data on 4.11 then use that data on 3.55 on the same console, requiring you to have a dual-boot setup to access PSN on 3.55. And if you have dual-boot, why would you want to do this?

That's what I said.

Because I want to help people, who don't have dual-boot.
We don't have to think selfish. If you help the whole scene, the ps3 scene will get more support and releases because its for bigger public.

The data you sniff from one PS3, will not work if you use it with another PS3.
And even if it did, the PSN server checks for this and would not allow two consoles with the same PSID to be logged in at the same time. It's like having one account connected at 2 different places on an online PC game.
Or maybe you plan on getting all the PS3's from people who want PSN on 3.55 and install an E3 flasher to sniff the data? :P

Haha lol no,
They must sniff it by thereselves, ofcourse with a bit more noob-friendly tools.

But if what <GEEK> said is true, then it is impossible without knowing the algorithm. The algorithm has nothing to do with the PS3 keys! Just telling this in case people think that.

It is not impossible to get the algorithm. But it will be a long process.

Edit:

lol ****, you owned me haha

Okay, okay, what I wanted is to run back-ups online on PSN.

The keys have everything to do with why we cant find out what the algorithm is. If the files were in raw format you could reverse engineer the algorithm.

So, to recap, you cant fake psn to think your on 4.11 on a 3.55 console w/o getting 4.11 keys and the encrypted algorithm. Console specific info is added to the encrypted data when it is sent to sony's servers. (i.e. Mac Address, PSID) As mentioned, if you have dual boot you could potentially do this because your Mac Address and PSID will stay the same from 4.11 and 3.55 since its the same PS3. But as also mentioned, this would make no sense if you had the ability to dual boot in the first place because you could switch as you please between homebrew and PSN. If you somehow were able to get packets from a 4.11 console and try to send them from a different console on 3.55 it would see that its using a different Mac address and not authenticate.


And as far as people being against PSN compatible CFW, what do you think is going to happen when eventually (be it 1 day or 20 years from now) someone creates a new CFW? It will be the same scenario. So although im against cheaters, im not against PSN on CFW because to be against that is to be against any new CFW as that is what would allow people to cheat again.

You don't need the PS3 keys. You need the algorithm which isn't impossible to solve. It is not like a md5 algorithm, because the PSN server can decrypt it, so then we can do it also. So it actually is possible to get the algorithm.

The reason why I try to get PSN on 3.55 is, because 3.55 can run back-ups.
I also am against cheating.

The only problem with this is that its like your trying to solve an equation with variables on each side.

X+Y=Z

Where X is the 4.11 keys, Y is the algorithm, and Z is the data that gets authenticated by PSN.

You cant solve this without at least two know vars. You wouldn't be able to brute force this either as this is most likely randomly generated each time it tries to authenticate.




I'm no PS3 expert but based upon what me and others have said so far in this post, its just not possible without knowing both the keys and the algorithm.

No, that has nothing to do with PSN. The keys are needed for running homebrew etc.
PSN is a whole different story. You only need to decrypt the packets.
