For quick internal tools on legacy networks, dropping OpenSSL 0.9.8 DLLs into your app folder still works. For any application exposed to the modern internet, you must either patch Indy 9 for TLS 1.2, upgrade to Indy 10, or implement a proxy architecture. For any application exposed to the modern internet,

Solution 4: Upgrade Indy (Most Robust, Highest Effort) Indy 9 is frozen in time. The modern Indy 10 (still maintained as open source) can be compiled for Delphi 7 with effort.
