Clear the S/MIME Recipient Certificate List

Demonstrates ClearEncryptCerts, which empties the recipient-certificate list previously populated by AddEncryptCert. This is useful to start over with a different set of recipients before calling EncryptN.

Background. The recipient list is internal state that accumulates across AddEncryptCert calls. ClearEncryptCerts resets it so a subsequent EncryptN encrypts only for the certificates added afterward.

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

JavaScript

var success = false;

var mime = new CkMime();
success = mime.SetBodyFromPlainText("This message will be encrypted.");
if (success == false) {
    console.log(mime.LastErrorText);
    return;
}

//  Add a recipient certificate.
var cert = new CkCert();
success = cert.LoadFromFile("qa_data/recipient.cer");
if (success == false) {
    console.log(cert.LastErrorText);
    return;
}

success = mime.AddEncryptCert(cert);
if (success == false) {
    console.log(mime.LastErrorText);
    return;
}

//  ClearEncryptCerts empties the recipient-certificate list, for example to start over with a
//  different set of recipients before calling EncryptN.  It is a void method.
mime.ClearEncryptCerts();

console.log("Recipient certificate list cleared.");
