Decrypt2

See more MIME Examples

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. C#

bool success = false;

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

Chilkat.Mime mime = new Chilkat.Mime();

// Load the certificate from a .cer file.
Chilkat.Cert cert = new Chilkat.Cert();
success = cert.LoadFromFile("aaworkarea/myCert.cer");
if (success == false) {
    Debug.WriteLine(cert.LastErrorText);
    return;
}

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

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

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

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

Debug.WriteLine("success!");
