Create private RSA key from String object

Question

I am trying to create a custom jwt token for firebase authentication from a C# WCF service. The problem is that I need to sign the jwt token with my private RSA key (e.g. "-----BEGIN PRIVATE KEY-----\nMIIEvQIBA ... wFg=\n-----END PRIVATE KEY-----).

How do I create a representation of the private key in String format (in brackets above) to a representation that C# understands?

are the \n in the Key String or representative of line breaks? — Jason Lind, Feb 11 '17 at 02:31
Then I really don't understand the question. If you already know the key and just need to place it in a string then it just needs to be wrapped in quotes — JasonLind, Feb 12 '17 at 03:02

As far as I konw, X509Certificate2 is not able to read a private key from a PEM base64-encoded file.

It is more easily to read the private key from the certificates. And refer to how to get private key from PEM file? about the detail.
