I think it's a dev tool for attempting to decrypt the 2.71 EBOOT file. As that is a ridiculously complex process requiring a huge amount of PSP know how, I think this is an app that you should only use if you are on the Dark_Alex/Booster/MPH level of PSP knowledge.

People who know more about PSP modding than you or me or most people on this forum.

No.

This is the key to decrypting the 2.7 firmware.

Yes by doing this they may find holes in the security of 2.7.

But more importantly (if you have a 1.5 that is), this will allow us to emulate firmware 2.7 on firmware 1.5

And when that day comes I'll have a smile a mile wide, as I am sure many of the other 1.5ers on here will too. Not as much of an elite club as it was before, lol, but the more the merrier! Everyone can join the 1.5 party! There's cake and icecream for all!

OK the firmware now is encrypted. Right? This means this:
Quote:
In cryptography, encryption is the process of obscuring information to make it unreadable without special knowledge. While encryption has been used to protect communications for centuries, only organisations and individuals with an extraordinary need for secrecy have made use of it. ...
So we can not read it without first decrypting it.
Quote:
The converting (as a coded message) into intelligible form by decodeing or deciphering.

No! ...

If you dont get any of the stuff I said before. Just get this into your head: decrypting the firmware allows it to be emulated.

Sorry but I dont think I can explain it better.
