Hello,

You can check the demo in the folder "Demos\01.WebSocket_Quick_Start\01.Server_and_Client_Chat" which shows a server and client components which can connect any of the openssl libraries: openSSL 1.0.2, 1.1.1 and 3.0.0
You only must select the openssl apiversion before start the server/client.

Sergio thanks for your answer! Indeed I found it in the sgcWebSockets but now I have another more general question, how do I switch to an Indy version from the project https://github.com/IndySockets/Indy to be able to use OpenSSL 3.* everywhere in my project, not only in sgcWebSockets ?

Hello,

The standard indy version doesn't currently support openssl 3, although there is an effort for provide support to it.
You can download the sgcIndy version which supports openssl 1.1.1 and 3.0.0
