Load a Private Key from a PKCS #1 File

Demonstrates the Chilkat PrivateKey.LoadPkcs1File method, which loads a private key from a file. The only argument is the file path. Despite the historical PKCS #1 name, it accepts any supported unencrypted private-key representation.

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: PKCS #1 is the older, RSA-specific key format — the BEGIN RSA PRIVATE KEY block still common from OpenSSL. This method reads it, and like the other content-inspecting loaders it also accepts other unencrypted representations, so it is forgiving of what is actually in the file. For unknown or mixed formats, prefer LoadAnyFormatFile.
