How to transfer client data encryption from one server to another?

Question

Digital certificates

Hello!
Please tell me what can be used for the following task:
an SSL client that sends a certain string to the server and receives a response. In this case, each session with the server comes from different users (one user - one certificate).
I didn’t quite figure it out, maybe stunnel, but in it I understand that there is only one certificate per connection, and I need to substitute certificates for each session (user).

Answer 1

Make your private SSL tunnels through your code inside a regular SSL connection.
Those. public shared SSL encapsulates other private SSL connections that are generated through regular hosting scripts (PHP, etc..).
It will be easier than reconfiguring the standard infrastructure from server to server, from hosting to hosting.

Answer 2

Do you need the server to present itself with a different certificate each time? Well, generate it every time - you still use self-signed ones.
