I’m trying to come up with an interopable crypto algorithm (by interopable I mean the ability to sign/encrypt data in c# using keys generated by JS and vice-versa).
I took ECDSA as a base as it looked modern and well-documented, I also saw sample keyUsage values, implying the encryption support (which I believe works quite well in JS).
I was able to sign/verify signatures in c# using JS generated keys, but c# ECSDA class doesn’t seem to support encryption. Is this WIP on MS behalf or we should stick to RSA for encryption (As this answer suggests)?
