Description

For a connection to an external api(https://developer.amazon.com/de/docs/amazon-pay-api-v2/signing-requests.html), I need a signature for authentication, which is created with the RSASSA-PSS algorithm.

As far as I know, the existing RSACryptoServiceProvider implementation does not offer the option of specifying the PSS padding. My online research has also shown that this is not possible either.

Therefore, I would like to add my own implementation of the "SignatureAlgorithm" interface based on the "System.Security.Cryptography.RSA" class.
For my use case, only a function that signs the data is sufficient. However, I think that the interface implementation is more similar to the styleguid.

I have fully implemented the interface functions. However, I have to say that I am not an expert on this algorithm.

I will provide the implementation for this BC Idea

As the idea is brand new, I need to wait a couple of days before I can triage this. It takes a while before ideas flow through the entire system 🙂 But I'll be on it soon!

One more PR coming. Re-opening.
