Load an Encrypted Private Key from a PEM File

Demonstrates the Chilkat PrivateKey.LoadEncryptedPemFile method, which loads a private key from a file, using a password when 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: The file-based encrypted loader — the natural choice for a .pem key stored with a passphrase, as most deployment keys are. It decrypts encrypted PKCS #8 PEM and also accepts unencrypted files, so it works whether or not the specific file is protected. Supply the passphrase from a secure source.
