Load a Private Key from a Microsoft PVK File

Demonstrates the Chilkat PrivateKey.LoadPvkFile method, which loads a private key from a Microsoft PVK file, using a password if the key is encrypted. The first argument is the file path and the second is the password.

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: PVK is a legacy Microsoft private-key format, historically paired with SPC certificates for Authenticode code signing. You encounter it mainly when working with older Windows toolchains; for anything new, PKCS #8 or PEM is preferable. This loader reads PVK and participates in Chilkat's content auto-detection, decrypting with the supplied password when needed.
