February 4, 2012 // 4:04 am - Following up on the previous update, this weekend Spanish PlayStation 3 developer Calantra has released a homebrew application to find PS3 Keys dubbed Lv0 Assault followed by updated versions below.

Download: PS3 Lv0 Assault v1.0 / PS3 Lv0 Assault v1.1 / PS3 Lv0 Assault v1.2 / qtintf.dll (Required)

To quote, roughly translated: LV0 assault is an application that uses the contents of any file type to search for valid cryptographic keys to decrypt files encrypted with keys LV0 metldr * or *.

What it does:

The operation of this program is not based on the use of the techniques of "brute force" is limited to just keep trying all possible keys of 32 bytes that can be found in a file.

We can get:

If by chance the key LV0 appear in theory you could decrypt the file LV0 content updates and versions higher than 3.56 contain changes which in turn contain the long-awaited keys.

That does not do:

  • It is used to decrypt any file type.
  • It serves to create any CFW.
  • There used to play GT5 and to play for PSN.


If we find the key delv0 ideally, the most dense file-level data as possible, these files are those that are compressed or encrypted. It is also very useful for finding keys if you have memory dumps from the localstore.

It should be clear that it is extremely difficult and unlikely to get the key LV0 by this method, but it's better than sitting in front of the screen waiting for the prophet down the mountain with the solution to your problems. The more people looking the better.

This program is experimental and is based on a complete utility that I used some time to locate and catalog keys. There are more explanations in the file "readme" that comes with the program and contact addresses.

How to use:

Click on menu "search for" select the lv0 to find lv0 key, metldr to find metldr key.

Thanks to:

Al the ps3devwiki contributors, Team Fail0verflow, Kakarotoks, at all of them for share their knowledges

Last of all, execuse me a lot for my bad english.

Regards, Calantra.

Well, if you know the encryption-type and write an CUDA / OpenCL program for GPU bf'ing, I would rent the Amazon EC2 quadruple GPU solution.

It's a reference to an "old-school" joke from the times of original PSJailbreak/PSGroove

"There used to play GT5 and to play for PSN."

It would be easier if sony simply gave the code lol

I told you 75 billion times not to exaggerate.

I understand your point, but the author knows this, that's why he says it's better to have something to do than magically waiting for cfw to be brought on a velvet pillow. Mathematically it can be calculated, and you may get lucky at some point and find it early (which is part of the point). But yes, realistically it would take entirely too long to do this.

Not sure about Sony's massive 32 byte keys, though. Holy cow! Maybe we should build a bank of PS3s with OtherOS and use the cell to break it.

Even if we ALL had 1 million computers dedicated to this and we ran it nonstop. Considering that its 32 bites, it would quite literally take 7 hundred million lifetimes to brute force. You can rule out the 000000000000000's and the 1111111111111111's but every combination following would take such a substantial amount of time.

And then even if we lived that long, our keys are perconsole. The algorithm that the games are signed with figures out our individual key using 2 keys that sony put in there. Even if this program used the algorithm it doesn't matter, because it needs 2 pieces of information it doesn't have. So it just starts guessing, from beginning to end.

It's pretty impossible to find 3.6+ keys with this tool, forget-it !
