(Lianja) Send Encrypted Email to Multiple Recipients

Demonstrates how to create and send an S/MIME encrypted email to multiple recipients. The digital certificate of each recipient is required. The encrypting/sending process uses each recipient's digital certificate (which internally contains the public key). Each recipient decrypts the received email using his/her private key.

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// Load each recipient's certificate into a Chilkat certificate object.
// This example loads the certificates from files.  However, the Chilkat
// certificate object provides other means for loading certificates,
// such as from in-memory PEM strings, or in-memory binary DER encoded form, etc.
