.MAP Resigner?

[Halo117]

I have one question about this so called .MAP resigner... How does this generate does it even generate or is it just a simple code? Because if it is a simple code cant you just use that other Halo 2 resigner and put the code in there? Oh and what does it generate off of... Is that what we are trying to find out or what?

There is no real .map resigner. If it was that simple dont you think it would have been done by now?

[Slidell]

theres no real map resinger it would be harder than that to make it and probley realy hard to use

[Dark Slipstream]

They have a real .MAP signer, you also need a .MAP Encrypter and a LIVE resigner. :/

[iBotPeaches]

And to clarify the encryption in Halo 2 was no encryption just the CRC checksum. Now were dealing with real RSA junk.

 

Point being, its 10000x harder than before and Halo 2 .map resigners will not work. They probably can resign the crc, but that doesn't matter. Johnson did that on its BETA release!

[LXV Grizzly]

What do you mean "They" have a .map resigner?

[Halo117]

What do you mean "They" have a .map resigner?

 

What I mean is how does the new resigned code be generated? Like the CON its resigned off of a keypair... Is a .MAP resigner going to be like that when/if one comes out? Or am i just totally wrong... LOL

[Justrec]

What do you mean "They" have a .map resigner?

He means Bungie has one.

[Slidell]

there wont be a map resiner release for a long time and then some bungie guy that got fierd and is pissed will be the one to reles it or someone might find out how too do it

[Halo117]

I would try to make one but I would need ALOT of help and ALOT more info on this so called .MAP Resigner? If Bungie made one why can't we! I bet if all us modders worked on one project we could problably do it... I mean its not like one bungie member just randomly made some .MAP Resigner!

First of all does anyone know the difference between a Halo 2 .MAP file and a Halo 3 .MAP file?

[SmokiestGrunl]

There is more security on a Halo 3 map then a Halo 2.

 

Here is what peaches has said earlier in this thread.

And to clarify the encryption in Halo 2 was no encryption just the CRC checksum. Now were dealing with real RSA junk.

Only very trusted bungie members know the key. Its not like they give it to the janitors and when one gets fired he will release it. Plus if this were to happen he would be sued up the ass and i dont think a bungie member would be stupid enough to do that.

[Halo117]

So is it a single code for each map?

[Halo117]

What do you guys mean by SECURITY like the kind of security where it wont let you access the files code? The kind of security that is REALLY hard to get to the codes? Or what? Ohh and one more question... Would we have to take the MAP file off of our Xbox's of can we just use the one that we use to open Johnson 1.4 with?

[SmokiestGrunl]

Ok I'll try and make it simple.

 

You want to enter a building, this building has a security guard. The guy says you can enter without showing and ID, but if you change something within the building you have to show your ID, or the building will get shut down.

 

or

 

You can access a computer without a password, but if you change a file on the computer and don't enter a password you computer will turn itself off.

 

or

 

Fixing the security checks within a map makes the game think that bungie made the map.

yeah thats why i said that wouldnt happen no bungie guy would be that stupid and youd need alot o practice to even begian to use one

[Mcmodder♥]

i realy wont a LIVE resigner if some one can get me one

[Halo117]

I know what you guys mean BUT IS IT JUST ONE CODE THAT REPLACES WITH ANOTHER OR DOES IT CREATE DIFFERENT CODES AS IT GOES!

[ILIKETURTLES♥]

Research RSA 2048, thats what is stopping us, we cant crack it. Not even the worlds most powerful super computer can crack it. Unless someone at bungie leaks the key we can not .map mod ( without a devkit). Even if we did get it we would still need the key the signing algorithm

[Halo117]

So someone tell me how a Development Kit can run a unsigned key but yet our normal Xbox 360 cannot someone tell me what makes the Xbox 360 Development kit be able to run a unsigned key tell me but don't just say the files are different what I want to know the key in the file that makes it be able to bypass all of that stuff!

"Modified XEX

 

The Xbox 360's games are written in a format that is very similar to a PC. The game files are stored in a directory, and have .dll files as libraries as well as an executable, much like a computer. Although, instead of .exe files these are called .Xex files, aka Xenon Execuables. These files are specially compiled by Microsoft Xbox 360 SDK, and are illegal to distribute as they contain copyrighted code. You may be asking, what does this have to do with Halo 3 modding? Well, When you select a map in the mainmenu, the executable for Halo 3 uses the RSA public key for the .map files, to verify that they are unmodified. If the files are unmodified, the XeX allows the map to be loaded. Otherwise, the Xex will not allow the map to be loaded and will result in a 'You have failed to load the map' error. Anthony, Xenon/Detox, and Kornman have gotten around this by mapping out the Halo 3 XEX file, and removed the check, in PowerPC based Assembly Language. This allows them to load any map files.

 

 

Real Time Memory Editing

This method has been described very briefly before, so I will try to clarify it as much as possible. A development kit is capable of running two processes at once, one being the current Title and the other being the network debug monitor. Xenon/Detox realized this and decided to use it to his advantage until he created a modified XeX. In this method, the XeDK ( Xenon Development Kit) loads an unmodified version of Halo 3. The player then goes into an unmodified .map file, and begins gameplay. Now remember, a XeDK can run two processes at once. Xenon used this to his advantage by writing a program to send commands through the network to his XeDK. He would mod his map on PC, and tell his XeDK to 'synchronize' with the PC version of his map. The PC would send these changes over the network and would be reflected immediately ingame. This is where the term, Real Time Halo is coined from.

 

 

 

 

Section 2 - Xbox 360 Development Kits ( XeDK )

Both of the above methods require one to have an XeDK, this is because an XeDK can boot in-progress games aka XeX files. For method 1, the user will simply transfer their modified XEX to the Halo 3 section of their XeDK or Dvd, and run the game on the XeDK. Method 2 requires an XeDK because retail units do not have network debug capabilities.

 

 

Some common misconceptions are:

the 'Hybrid' Xbox 360 : This was a term coined in the early stages of modding when it was believed Microsoft would bring trouble to any one thought to possess an XeDK.

the Demo Kit: The Demo Kit is one of many types of Xbox 360 Development setups. Some of the most common set ups for these are:

1. the Demo Kit

2. The Reviewer's Kit

3. The Testing/Debug Kit

4. The Development Kit

 

All debug hardware offers the functionality required for Halo 3 modding. None of these kits can access Xbox LIVE service, They access a service called XePartnerNet.

 

It is recomended that you DO NOT purchase these items, as there are many additional software tools required to mod Halo 3, and it is a waste of hardware for actual developers and people who have legitimate other uses for them.

 

 

 

 

 

Section 3 - Why This isnt Possible on Retail

At this point the question may be coming into your mind, ' Why cant we just Resign the maps like Halo 2?'. Halo 2's .Map files were protected via a CRC Checksum. This is basically a string of hex written to the file telling the game what the files signature should come out to be. Halo 3 has a much stronger form of protection on the maps called RSA. This is a method of encryption/signing a file based on two keys. One of these is the public key, and the other the private key. Each key has a different function. The key we can access, the public key, is used for verifying a file is unmodified. The private key, which only bungie has, is used for signing/encrypting the files to be verified by the public key. This key is an RSA 2048 bit key, mathmatically designed to be impossible to crack in our lifetimes, thus raising the need for a method of bypassing it."

Soo your saying that with a development kit they modify it while in game? SWEET Edited August 27, 2008 by Halo117

[Guest pRoX]

dont flame me on this or quote me on this, but im just thinking outside the box.. dont you think they have done sometyhing serverside because they learned their lesson with halo 2? maybe the "code" for each map is ran against a serverside list of codes, so say if someone starts modding they change all the server side codes and whoever is still using the old "codes" on their map after everyone got the new update then they get banned...idk im just thinking they had to think something up after halo2 was ruined by thousands of modders...

They would need to recreate a whole new Halo disk and a whole new RSA encryption.
