Load a Private Key from BinData (Any Format)

Demonstrates the Chilkat PrivateKey.LoadAnyFormat method, which loads a private key by inspecting the bytes in a BinData. The first argument is the BinData and the second is the password (used if the detected key is encrypted).

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: When you have key bytes in memory but do not know their exact format — downloaded, decrypted, or pulled from a database — this figures it out for you, recognizing PKCS #1/#8 DER, encrypted PKCS #8, PEM, JWK, Chilkat XML, Microsoft formats, and more. It removes the guesswork of choosing a specific loader, at the small cost of the detection step. Supply the password so it can decrypt an encrypted key without a second call.
