Load a Private Key from PEM Text

Demonstrates the Chilkat PrivateKey.LoadPem method, which loads a private key from PEM text. The only argument is the PEM string. It has no password argument, so it cannot load an encrypted PEM — use LoadEncryptedPem for that.

Background: PEM is the Base64 text format (delimited by -----BEGIN----- lines) that most tooling uses for keys. This method is for the plain, unencrypted case where the key material sits in the clear inside the PEM — convenient, but it means the file itself is the only thing protecting the key. When the PEM is password-protected (a BEGIN ENCRYPTED PRIVATE KEY block or a legacy encrypted header), reach for the Encrypted loader instead.
