As a professional Web Developer I having a hard time deciding whether I want to keep my 1.5 so I can homebrew vs. upgrading to 2.0 so I can develope stuff on the Web for the PSP.

Sony, why did you have to make such a tough choice!!!!

i almost had it, but i guess not. i might be able to figure it out if i know what out.append((char) was and & 0xf was, im sorry, but i don't anything about java, except it seems to be alot like c++. out.append appends the character "char" into the output. and "& 0xf" is ...

Signing in this case makes more sense. The AES encryption is mostly for the wireless (prevent sniffing, spoofing and general cheater mayhem), but it is a great tool for ensuring that a signed binary remains trustable. As I have stated before, Sony's goal is to ensure that devs go through them (and ...

If I had a 1.0 firmware I would definately dump out a BIOS be going down this route. Alas I don't and can't :-(

I looked up some info on PGP ecryption. and from a website I got this quick case. Lets say youw want to send Allice an encrypted message 1. You say to PGP that it has to encrypt a message with the Alice's public key 'APK' 2. PGP creates a new temporary secret key 'TSK' randomly 3. PGP encrypts the m...

well i guess it was brought up. but has anyone have any luck trying to find this encryption function in the BIOS? this work depends on finding and being able to run the encryption function on a 1.0 PSP. If we can't do this then this thread and the one mention just now are both useless.. except for p...

is there a difference between a game save and a ghost save? and what is it? whatever ghost saves are I'd still try to focus on game saves.

I'm going to test this as soon as I find someone with another PSP. in the meantime if anyone else can confirm this save game transfer issue it would be great. I was also looking at the firmware directory dump in the other treads and i believe the best place to start would be: flash0:\vsh\module\ 602...

I believe it's already a fact that encrypted gamesaves are signed against the PSP, not just the game (that is, gamesaves are non-transferrable between PSPs). serious? that sucks... wait that means you can't swap your memory cards like you can on the PS2? that doesn't sound right. oh well i guess it...

The problem here is that people are assuming the encryption is as simple and careless as something like CSS which is not the case. With BSAFE and Verisign being used, and possibly asymmetric encryption to protect symmetric keys... it makes CSS look like a toy (which it is). Well I'm not saying tryi...

I was not trying to get the 1.5 firmware decrypted. I was trying to get encrypted binaries from a 1.0 PSP so that it can be run on a PSP with a 1.5 firmware. because the 1.5 firmware only executes encrypted binaries.

If, and this is a big IF, all save game data is encrypted. That means that the encryption function could be in the bios. Could we get the address of that on a 1.0 firmware and use it, like nems did with sceDisplaySetMode, to encrypt a saved game data with a buffer-overflow exploite of some kind. the...
