C#/CSharp Example

The following code demonstrates how to verify S/MIME digital signature and decrypt encrypted email.
Code:

// The following example codes demonstrate parsing S/MIME email - digital signature and decryption
// To get full sample projects, please download and install EAGetMail on your machine.
// To run it correctly, please change email server, user, password, folder, file name value to yours

using System; 
using System.Collections; 
using System.Collections.Generic; 
using System.Text; 
using System.IO; 

// Add EAGetMail namespace
using EAGetMail; 

namespace receiveemail

        { 
            Mail oMail = new Mail("TryIt"); 
            oMail.Load(emlFile, false);

                    // This email is encrypted, we decrypt it by user default certificate.
                    // You can also use specified certificate like this
                    // Certificate oCert = new Certificate();
                    // oCert.Load("c:\test.pfx", "pfxpassword",
                    // Certificate.CertificateKeyLocation.CRYPT_USER_KEYSET);

                    // Then you can use send the encrypted email back to this sender.

Hello!
I was very interested in this example code, with its help I was able to get data about signatures in a letter in which the Bat sees nothing.
But I have a question. The thing is, I'm dealing with letters that may have more than one signature. In this case, how can I get data about all certificates?

Hi, very few email has multiple signatures, could you send an email to support@emailarchitect.net for assistance?
