So key_decript is the code for signing homebrews on the PSP right?

the only thing you can do with "new keys" from psvita's pspemu is decrypt latest pspemu flash files.
signed eboot.pbp files and such already work without any change to signed ones for 6.60 psp, indeed you can load them without supporting unsigned modules from pspemu using kernel exploit (since kxploit is the only way to reboot with other apps, even loading signed eboots requires kxploit, but it's much easier to reboot on since there's no need to enable unsigned apps)

I already posted an updated version of psp cipher with some pspemu "new keys" to decrypt latest pspemu flash files previously actually, and if you look you can see the main.c file in my updated pspcipher code (originally by virtuous flame) already contains most the code and keys you can see in this "updated" key_decrypt.c file :mrgreen:

Oh, so that is what it is all about!
So, you get a kexploit, dump the flash0, then transfer it to the PSP, decrypt using PSPCipher?

Ugh... How many times have we answered these questions? This has nothing to do with finding kernel exploits. You FIND a kexploit by reverse engineering the PSP OS, installing this on your PSP will not magically give you a kexploit on the Vita :| and you can't install this on your Vita :roll:

yes exactly
you could decrypt on psvita too but not worth the pain for people who own a psp ^^

How do you get keys from flash if you dont got them in first place to decrypt flash? :roll:
Or they are obtained from somewhere else ?
