Load a Private Key from XML Text

Demonstrates the Chilkat PrivateKey.LoadXml method, which loads a private key from XML text. The only argument is the XML string. Supported roots include RSAKeyValue, DSAKeyValue, ECCKeyValue, and Ed25519KeyValue.

Background: XML key representations such as RSAKeyValue come from the .NET/XML-DSIG world, where keys are exchanged as XML elements. This loads that form — the inverse of GetXml — which is handy for interoperating with .NET code or systems built around XML signatures. It is a plaintext format, so protect the XML like any unencrypted key material.
