Set Cert and Private Key for S/MIME Decryption

Demonstrates the Chilkat Imap.SetDecryptCert2 method, which specifies a certificate together with a separately supplied private key for decrypting S/MIME messages. The first argument is the Cert and the second is the PrivateKey. This example loads the certificate and key from separate files.

Note: The certificate path is relative to the application's current working directory. Supply the path to your own certificate file.

Background: Sometimes the certificate (the public part) and the private key are stored separately — a .cer alongside a PEM key file, for instance. This method pairs them explicitly, whereas SetDecryptCert expects a single Cert that already provides its private key. After the pairing, subsequently downloaded S/MIME messages are decrypted automatically.
