EBOOT.PBP not encrypted?

[TheBuzzer]

Is the eboot.pbp not encrypted but the thing that is is the data.psp file?

and is there any way to decode the data.psp file?

[eternalis]

Nope the eboot.pbp is not encrypted. It can easily be extracted using PBP Unpacker or a similar program.

The data.psp file is encrypted. So we can not decode the file without Sony's encryption key.

EDIT:
OK, now I'm not so sure due to this:

- Decrypt the data.psp file using a decryptor (it needs to be able to decrypt files with a file size of several Mbytes, I use my own decryptor to do so but there might be other decryptors (available publically) having the same ability, otherwise just code your own from the psardumper sources)

data.psp can be decrypted using prxdecrypt sample in PSPSDK - although, if the data.psp is encrypted with a fw 2.6/2.7 key you may have to edit the source and run it on a 2.6 unit.
