    // Note: In the Apple Keychain, a certificate with its private key represents an identity because it combines the certificate and its private key.
    // When Chilkat loads a certificate from the Apple Keychain, it also gets the associated private key.
    // You can simply use the cert in other places in Chilkat where a cert w/ private key is required.
