vCardContact.Security.Key

Hello
VCardSecurity has SaveToPEM but not LoadFromPEM, instead it has vCardContact.Security.Key which is a string property, means we need to convert the public key to string and encode as Base64, shouldn’t be a X509Certificate2 instead?
Anyway, how to load a X509Certificate2 into the vCardContact.Security.Key?
Thanks :slight_smile:

Cause

The vCardContact.Security.Key property is designed to hold a string representation of the public key, which typically requires encoding in Base64. The absence of a LoadFromPEM method in VCardSecurity indicates that the library expects you to handle the conversion of your public key into the appropriate format manually.

Solution

To load an X509Certificate2 into the vCardContact.Security.Key, you will need to extract the public key from the X509Certificate2 instance, convert it to a Base64 string, and then assign it to the Security.Key property.

Code

Here’s a code snippet demonstrating how to achieve this:

using System;
using System.Security.Cryptography.X509Certificates;
using Aspose.Email.VCard;

public class Program
{
    public static void Main()
    {
        // Load your X509Certificate2
        X509Certificate2 certificate = new X509Certificate2("path_to_your_certificate.pfx", "your_password");

        // Extract the public key
        byte[] publicKeyBytes = certificate.GetPublicKey();
        string publicKeyBase64 = Convert.ToBase64String(publicKeyBytes);

        // Create a vCardContact instance
        VCardContact vCardContact = new VCardContact();

        // Assign the Base64 encoded public key to Security.Key
        vCardContact.Security.Key = publicKeyBase64;

        // Now you can use vCardContact as needed
    }
}

Next Steps

  1. Ensure that the path to your certificate and the password are correct.
  2. Test the code to verify that the public key is correctly assigned to the vCardContact.Security.Key.
  3. If you encounter any issues, check the format of the public key and ensure it is compatible with the expected input.
