Well the counterpart is a government section… so i highly doubt i can make them change their flow. they mentioned using an integrated sofware as a plugin in outlook.
they use a software called “Symantec Encryption Desktop”
i guess the plugin just takes the reply written by the clerk and generates the —PGP— part out of it and pastes that into a mail as inline text or something like this. and i guess the inline copy also has to do with the fact that the shared mailbox cannot be encrypted directly only via the key of the clerk using it and they do not want to share the public keys from all workers separatly
