Set the Decryption Certificate and Private Key

See more Email Object Examples

Demonstrates the Chilkat Email.SetDecryptCert2 method, which explicitly provides a certificate and its corresponding private key as separate objects for decrypting a received encrypted email. Set them before loading the encrypted message. This example loads a .cer certificate and a PEM private key, sets both, then loads an encrypted email.
