Set the Decryption Certificate for an Email

See more Email Object Examples

Demonstrates the Chilkat Email.SetDecryptCert method, which explicitly provides a certificate (with access to its private key) for decrypting a received encrypted email. Set the certificate before loading the encrypted message so Chilkat can decrypt it automatically. This example loads the certificate from a PFX, sets it, and then loads an encrypted email.
