Hi,

I wrote a redirector which redirects all 80/443 port to my proxy in Delphi. I am handling all socket data/connection. What i need is to filter SSL traffic. I need some advice before ordering.

My questions are:

1. Client sends data to port 443. Server receives this data but it is encrypted. How can i decrypt this SSL data to see what hostname and url client is trying to connect? I can already the existing data to server without modifying it. But when I receive data from server, how can i again decrypt it (to check for title)?

2. When we use this VCL to encrypt/decrypt, is browser going to prompt untrusted certificate dialog box?

3. Again, using our own sockets which is coded using Winapi, how can i create a client request, send to server and decode incoming data from server?

Please kindly advice.

Bests,

It is impossible decrypt SSL data because it will be breaking of SSL protocol.
If you want to implement the following schema - user connects to your own SSL server, your server decrypt data, processes and sends it to the external SSL server via the new created connection - then you need to implement SSL server, because SecureBridge doesn't support SSL server.
