ROM Hack Tool to validate a CIA file?

[cearp]

Are there any tools out there that can check to make sure all signatures in a cia (tmd, ticket, contents etc) are valid and not tampered with?
I searched a bit and saw something some fw/system update cias, but when I looked closer it was just verifying the actual hash of the file.

I suspect there is something out there already which can do this, as 3ds crypto has come so far, but haven't really been following all the developments so closely.
If there isn't anything, any pointers on which key(s) I'd need in order to verify the signatures and data?
Thanks

You can check tickets from 3ds and wiiU on authenticity
ticket_check.py <ticket.tik>
Receive one of two messages FAKE or ORIGINAL

Earlier I had the idea to make a collection of original tickets from different consoles 3DS, it will allow can download games from Nintendo servers directly. In fact freeshop2.

How do you run this? It's not working when I try it.
