Load a Public Key from a File

Demonstrates the Chilkat PublicKey.LoadFromFile method, which loads a public key from a file. The only argument is the file path. Chilkat examines the file content rather than the extension, accepting binary DER, PEM, Chilkat XML, JWK, and other supported representations.

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 most convenient loader when a key sits in a file of unknown format — it reads the bytes and detects DER, PEM, XML, or JWK without you having to match a format-specific method. Because it keys off content rather than the filename, a mislabeled extension does not trip it up. This is the pragmatic default for applications that accept public keys from users or varied sources.
