Reusing registered accounts

As I understand it, a Let’s Encrypt account only needs to be registered one time. So if I call:

var account = await client.NewRegistraton($"mailto:{Email}");

I need to save the account so I can re-use it on future registrations. (According to the LE documentation there is a penalty for registering a single account too many times.) I can re-use the registered account by calling the Use method:

client.Use(account.Key);

What I can’t figure out is how to save the key in my database so I can re-use it later. The key is a type KeyInfo but it only contains one property “PrivateKeyInfo”. I can store this byte array but I need a way to turn it back into a key. Do you have any examples of how to do that?

Perfect! That is exactly what I needed.

Thanks also for all of your hard work creating this library. It’s made my job a lot easier.
