I Just try to enable SSL for bitcoin-qt RPC call. I follow the SSL on RPC link to archive my target. But I am getting the following error and close the bitcoin-qt automatically.
I am using the bitcoin-qt 0.16.3
Support for SSL protected RPC was removed in Bitcoin Core version 0.12.0 (released in february 2016).
See https://bitcoin.org/en/release/v0.12.0#rpc-low-level-api-changes for the release notes on this, and also a workaround.
