I run bitcoind 0.17 in a particular port of the Ubuntu 18.04 VPS server. I want to give the SSL certificate for the RPC port. I already know how to generate a self-signed certificate with OpenSSL. But I do not know how to apply SSL on a particular port. Please give an idea about this.
Also refer to the following link to apply SSL to the Apache Help.
But it does not work. I think it's an old document. All new documents are available to archive my target.
