A: For newer Delphi versions (Delphi 2007 and later) and Indy 10, you should use standard OpenSSL 1.0.2u libraries, which can be obtained from https://indy.fulgan.com/SSL/ . If you encounter issues even with these, try using the WhichFailedToLoad() function to identify the specific problem. Newer versions of Indy 10 generally support OpenSSL 1.0.x and 1.1.x, and OpenSSL 1.1.x is recommended for better security. Configure Your Delphi 7 Code He dug through

Indy 9 is an older library. Modern versions of OpenSSL (specifically the 1.1.x and 3.x series) have different function signatures and filenames compared to what Indy 9 expects.

This function returns a string indicating exactly which export function or library failed to initialize, verifying if the issue is a corrupt DLL or an invalid version version mismatch. Severe Limitation Warning: Modern TLS Compliance

Test 1: Fail. Test 2: Fail. Test 3: "Could not load SSL library." Test 4: The program hung completely. He had to kill the process.

Indy 9 in Delphi 7 does not have SSL/TLS capabilities built directly into the components. Instead, it acts as a wrapper around external OpenSSL dynamic link libraries ( .dll files). The error occurs when:

var IdHTTP: TIdHTTP; SSLHandler: TIdSSLIOHandlerSocket; begin IdHTTP := TIdHTTP.Create(nil); SSLHandler := TIdSSLIOHandlerSocket.Create(nil); try // Link the SSL handler to the HTTP component IdHTTP.IOHandler := SSLHandler; // Set SSL Options SSLHandler.SSLOptions.Method := sslvTLSv1; // Or sslvSSLv23 depending on server compatibility // Make the secure call Memo1.Lines.Text := IdHTTP.Get('https://example.com'); finally IdHTTP.Free; SSLHandler.Free; end; end; Use code with caution.
