| Summary | 0002677: HTTPs should enable validation check to prevent MITM attacks | ||||
| Description | To prevent MITM attacks the server should send the expected hostname or include it in the certificate. The client should verify the certificate and sent a response containing "I validated you as server with hostname x.y.z" If the server receives the response with the correct hostname it responds otherwise it disconnects | ||||

| related to | 0002910 | closed | Matthias Wachs | Add a option field to transport addresses |
| We also should add a few bits to the other transport addresses to support things like the SilentKnock feature. Maybe it is time for a generic "options" word to be added everywhere to all addresses, so we can be backwards-compatible in the future? | |
| Implemented in: tcp udp http(s) client / server | |
| Implemented: Servers sets option to verify certificate in address, client extracts option and tells curl to verify certificate. But there is no way to interact with curl while verifying the certificate: Connection fails if connection cannot be verified | |
| That sounds fine, if validation is on and cert fails to validate, connections should fail IMO. So is this 'fixed'? | |
| I think note 7197 can be misunderstood: The option to verify is included in the address, not the certificate itself. So an attacker can create a valid certificate for the hostname the server uses. | |
| Implementation as described above fixes the problem | |
