I think its better if you provide more information like whether you on on-prem, AMS or CS.
This seems to be a tedious job and I have not seen anyone doing this. What kind of security threat you are seeing?
In case of
- On-Prem - You own both author & publisher. Then i dont think you need this as you habe full control of author/publisher which means you can control who can access your environments. And ideally you should have both author & publisher behind the fireball. I dont see a major issue here.
- AMS/CS - Environment owned by Adobe and we have seen many banking customers, financial domains customer who are using this without demanding the need to encrpyt the data flow b/w author & publisher.
It better, if you once more why this is needed? Is this really posing a threat to your system or data?
