to see if Indy is actually registering the library after you've placed the files. Modern Note:

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. Delphi 7 Indy 9 Could Not Load Ssl Library

// Critical for modern servers: IOHandler.SSLOptions.Method := sslvTLSv1; // Or try sslvTLSv1_1, sslvTLSv1_2 – but Indy 9 may not have these constants. // If not, use: IOHandler.SSLOptions.Method := sslvSSLv23; // Auto-negotiate to see if Indy is actually registering the

Indy 9 does not support standard, official OpenSSL DLLs. It relies on a heavily customized OpenSSL 0.9.6 build containing distinct exports specifically tailored for Indy 9. // Critical for modern servers: IOHandler

Indy 9 does not use the Windows SChannel (Secure Channel) like modern HTTP clients. It does not use the system certificate store. It relies entirely on a specific, now-ancient, version of the ( libeay32.dll and ssleay32.dll ).
