Export a Private Key as Traditional PEM

Demonstrates the Chilkat PrivateKey.GetPkcs1Pem method, which exports the key as unencrypted PEM, preferring the traditional algorithm-specific representation when one exists (for example -----BEGIN RSA PRIVATE KEY-----). It takes no arguments.

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: Before PKCS #8 unified key storage, each algorithm had its own PEM format — RSA PRIVATE KEY, EC PRIVATE KEY, and so on. Some older tools still expect that traditional form, and this method produces it. When you have the choice, PKCS #8 (GetPkcs8Pem) is the more interoperable modern option; use this for compatibility with software that requires the legacy layout.
