DegitalSigned email - Verify sender detail(signature) RRS feed

  • Question

  • Hi,

    We are using EWS (Microsoft.Exchange.WebServices) to communicate with exchange server. Now we have a  problem with digital signed email. We have a requirement to verify the digital signed email sender details. We are getting the mail item as ".p7m" and we are able to get the attachments and certificate as ".p7s" attachment.
    How can we verify the mail item details? What is the process to verify the digital signed email?

    Thanks & Regards,

  • Depends on your platform. You usually use a crypto library to do that, on Java you could use Bouncycastle for example.
