Export a Private Key as XML

Demonstrates the Chilkat PrivateKey.GetXml method, which exports the key in Chilkat-compatible XML (for example an RSAKeyValue element). It takes no arguments; the XML is not encrypted.

Note: The file paths are relative to the application's current working directory. Absolute paths may also be used. Supply the paths appropriate to your own environment.

Background: The XML key format belongs to the .NET/XML-DSIG world, where keys are represented as XML elements. Exporting to it is what you do to hand a key to .NET code or a system built around XML signatures — the inverse of LoadXml. It is plaintext, so the exported XML must be protected like any unencrypted key.
