PKCS7 Decrypt MIME

See more MIME Examples

Loads a PKCS7 encrypted MIME file and decrypts. The cert and private key used for decryption is loaded from a PFX file. C#

bool success = false;

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

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

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

// The AddPfxSourceFile and/or AddPfxSourceData
// methods may be called one or more times (one per PFX)
// to add sources from which the MIME component will
// search for certificates and private keys when decrypting.
string pfxPassword = "myPassword";
success = mime.AddPfxSourceFile("myCertAndPrivateKey.pfx",pfxPassword);
if (success == false) {
    Debug.WriteLine(mime.LastErrorText);
    return;
}

// Decrypt...
success = mime.Decrypt();
if (success == false) {
    Debug.WriteLine(mime.LastErrorText);
    return;
}

// Display the decrypted MIME:
Debug.WriteLine(mime.GetMime());
