Load an Encrypted Private Key from PEM Text

Demonstrates the Chilkat PrivateKey.LoadEncryptedPem method, which loads a private key from PEM text, using a password when the PEM is encrypted. The first argument is the PEM string and the second is the password. Unencrypted PEM is also accepted.

Background: An encrypted PEM protects the key material at rest — a stolen file is useless without the passphrase — which is why encrypted keys are preferred for anything shipped or stored. This loader supplies that passphrase to decrypt a BEGIN ENCRYPTED PRIVATE KEY block (and gracefully handles unencrypted PEM too), so it is a safe default when a PEM might be either. The password should come from a secure source, never a hard-coded literal.
