Load a Public Key from a String

Demonstrates the Chilkat PublicKey.LoadFromString method, which loads a public key from a string. The only argument is the string. Chilkat examines the content and recognizes PEM public keys, unencrypted PEM private keys (taking only the public portion), XML, JWK, and more.

Background: This is the forgiving text loader: rather than requiring you to know the exact format, it inspects whatever string you provide and figures it out. A useful convenience is that it accepts an unencrypted private key too and keeps only the public half — handy when you have a key pair but need just the public key. Use it whenever the textual format is uncertain or varies by source.
