Save a Public Key as an XML File

Demonstrates the Chilkat PublicKey.SaveXmlFile method, which saves the public key as Chilkat XML (the same text as GetXml) to a file. The only argument is the destination path.

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 file-writing form of GetXml, for interoperating with .NET or XML-signature software that reads XML key values. As a public key it is not sensitive, so the resulting file can be shared. No byte-order mark or extra line-ending changes are added.
