PGP email communicate with Secude
One client want to encrypt their email with PGP desktop email or gateway email. They have a very important partner who is using the SECUDE. The SECUDE encode is S/MIME. The partner used the Microsoft CA certificate to integrate with the SECUDE. However the partner had ten thousands of end users. It’s impossible to enforce end users to import the PGP key. So, how to communicate between PGP and SECUDE? Could PGP support the CA certificate, whatever desktop email or gateway email?
Anyone can help me? Thanks!
