(JavaScript) Decrypt2

Demonstrates how to decrypt MIME using a certificate and private key where the certificate and its corresponding private key are stored in separate files -- a .cer for the certificate, and a .pem for the private key.

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.

var success = false;

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

var mime = new CkMime();

// Load the certificate from a .cer file.
var cert = new CkCert();
success = cert.LoadFromFile("aaworkarea/myCert.cer");
if (success == false) {
    console.log(cert.LastErrorText);
    return;
}

// Load the private key from an encrypted PEM file.
// (A private key can be loaded from other file formats also..)
var privKey = new CkPrivateKey();
success = privKey.LoadEncryptedPemFile("aaworkarea/myPrivateKey.pem","myPassword");
if (success == false) {
    console.log(privKey.LastErrorText);
    return;
}

success = mime.LoadMimeFile("aaworkarea/encryptedMime.txt");
if (success == false) {
    console.log(mime.LastErrorText);
    return;
}

// Decrypt using the cert and associated private key
success = mime.Decrypt2(cert,privKey);
if (success == false) {
    console.log(mime.LastErrorText);
    return;
}

// Save the S/MIME to a file.
success = mime.SaveMime("aaworkarea/decryptedMime.txt");
if (success == false) {
    console.log(mime.LastErrorText);
    return;
}

console.log("success!");
