Simple answer lol the keys are in the ps3 with tough encryption so in the end its hard to obtain the keys

hmmm oke oke to bad i dont anything about programming

The PS3 uses a public-key encryption system..

There is one key that encrypts stuff (the public key)
And one key that decrypts the stuff (the private key) encrypted by the other key.

The games are encrypted with the public key, and then decrypted by a private key inside the PS3 firmware.. Even if there was a key in the eboots (and there most likely is not), it would be the public key handed out to companies to encrypt their games. I see no reason that Sony would ever hand-out the private key that no one else than the PS3 should know (as only it should be able to decrypt the retail eboots), to the gamecompanies.

So then does that mean that if there was a key to encrypt the games then if you knew what the key was you could mod/hack the game using itself? I'm just wondering

There IS a key to encrypt the games.
You can view it as this. Sony hands out treasure chests (public keys) to all the game developers to put their games inside, and gives their PS3 the key to unlock the chests. All game companies then put their games inside the treasure chest and distributes them. Whenever the PS3 receives a treasure chest, it uses its key (the private key) to unlock the chest and take out whats inside - the game, so that it can then play it.

thats the basic principle behind public key encryption. You have one key you hand out to the public to encrypt, and one key you keep yourself to decrypt it.

If we knew the (public) key that were used to encrypt games, we could not use it to mod or hack the game, as we couldnt decrypt the game and make changes to it. It would not be useless however, it would allow us to encrypt our own games/programs that the PS3 would read and accept.
If we had the private key the ps3 uses to decrypt the games, then yes we could modify and hack and cheat them and all that. it would, however, REQUIRE that we had the public key also, so that we could encrypt them again into their former form.

There are theories that what True Blue for instance does, is that they give the encrypted games to the playstation 3 and lets it decrypt the games using its unknown private key, since it knows how to. When it is then decrypted, they somehow dump the unencrypted game that are loaded into the PS3's RAM, and then encrypt it again with the known public key that were on 3.55, so that 3.55 games can play it. Perhaps (most likely), they also modify the eboots a little in their unencrypted forms, to make it compatible with 3.55. (Imagine you used a feature introduced in firmware vesrion 4.0 in a game that you had made. Some changes are needed to be done, to make a lower firmware version able to run it, since it wouldn't know that feature. It would have to be wrapped to the features of the lower firmware version somehow)
Again:
1. Their technique is perhaps they _somehow_ dump the unencrypted game from the RAM,
2. It is not sure they do it this way, there are many theories.
3. It is not known if this technique is practically possible or only theoretically (at least not to me). Some quite prominent people in the hacking aspects of the scene has, however, mentioned they are trying this approach out. Pretty cool huh

Hope it was useful

a little question to your post.
if i´m not wrong then only the eboots (we can say are the ps3 .exe) are encrypted and the rest of the game (video data or backround data etc.) has no encryptin right?
what about the psn games? couldn´t we use psn games on 4.x firmware to find an exploit by modding the gamefiles? IIRC the first jailbreak was possible because we could overload the ram. couldn´t we use this method too by changing same files from an installed PSN game to force it again or find some other ways to open the ps3 or find the keys? I ask this because I never heard/read that anyone tried to mod a game and then find a exploit or other usefull things
(sorry if this question is too OT)
