Load a Private Key from an XML File

See more Private Key Examples

Demonstrates the Chilkat PrivateKey.LoadXmlFile method, which loads a private key from an XML file. The only argument is the file path. Chilkat recognizes RSA, DSA, EC, and Ed25519 XML produced by GetXml, and auto-detects other supported unencrypted representations.

Note: The file path is relative to the application's current working directory. Absolute paths may also be used. Supply the path to your own key file.

Background: The file-based form of LoadXml, for a key saved as an XML file — typically one written by SaveXmlFile or exported from .NET. Because it also inspects the content, it will load other unencrypted representations if the file turns out not to be XML.
