what tells you CMA is encrypting / decrypting anything ?
I would say the ms itself contains encrypted files, it'd be kinda dumb to put any algorithm into CMA since we can RE it
This would mean even REing CMA wouldn't learn us anything about the encryption / decryption process, more likely imho


It is, but the crypto is done on the vita, not in the PC app.

Do you know of anybody that has tried this?
I have a little programming experience, and I would be willing to try it if its worth it. :)

Not too worth it, except for creating an open source CMA (that doesn't have the $ony backdoors). If you're willing to work on it, you can try finishing the Open Idea CMA. (tbh, if I had a Vita, I'd definitely be on it)

I posted when my computer was sitting for a while, so those posts were not there.

Very rude BTW.
