Add a Recipient Certificate for S/MIME Encryption

Demonstrates AddEncryptCert, which adds one recipient certificate to the list used by EncryptN. Call it once for each intended recipient, then call EncryptN to encrypt for all of them.

The file paths are relative to the application's current working directory. Absolute paths may also be used. Supply the paths appropriate to your own environment.

Background. AddEncryptCert builds up the recipient list used by EncryptN. Only the public key of each certificate is required for encryption.

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;
}

//  AddEncryptCert adds one recipient certificate to the list used by EncryptN.  Call it once per
//  recipient.
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;
}

//  EncryptN then encrypts for all certificates added.
success = mime.EncryptN();
if (success == false) {
    console.log(mime.LastErrorText);
    return;
}

console.log("Encrypted for the added recipient(s).");
