Using a previously generated RSA public/private key with the .net framework

Question

I have a pre-existing public/private key pair for RSA encryption which I need to use in .net . All the examples I can find online demonstrate how to generate a new private/p

I realise this is a very old question but maybe someone still looks at this...

Nowadays you can retrieve/store your keys in XML format (which you possibly could back in the days too).

Example import:

this.RSAKey = RSA.FromXmlString(xmlString: myRSAXMLKey);

Example export:

this.RSAKey_XMLString = RSA.ToXmlString(includePrivateParameters: false);
