Hi, is it possible to have a package VRC.Udon.Cryptography to have certain functions like bool VerifySignature(string data, string signature, string publicKey) or/and byte ComputeSHA256(byte data)

I’d love for VRChat to do that, but if you need something in the meantime I suggest using [UdonHashLib](https://github.com/scarletcafe/vrchat-udon-hashlib).  
It is not perfect, but does work for most basic needs.  
I personally use it to compute a hash signature with data received from a string download, then compare both the signatures to check if they match.
