Note: Using old libraries is not recommended for high-security applications due to known vulnerabilities. However, for maintaining legacy Delphi 7 applications, these are required. Look for libeay32.dll and ssleay32.dll . Step 2: Place the DLLs
Indy 9 cannot communicate with modern OpenSSL branches. It requires the legacy branch. Specifically, version 0.9.6m is widely recognized as the most stable release for Indy 9. Locate a trusted archive of legacy OpenSSL binaries.
The DLLs do not match the compiled architecture of a Delphi 7 application. Step-by-Step Resolution Guide Delphi 7 Indy 9 Could Not Load Ssl Library
is complex. Many developers instead use the TWinHTTPClient component (available in later Delphi versions, but you can port it) or simply call WinHttpOpen directly.
: You can manually copy the necessary DLLs (e.g., libeay32.dll and ssleay32.dll for older OpenSSL versions) to your application's directory or a system directory (like C:\Windows\System32 ). However, be cautious with system directories to avoid compatibility issues. Note: Using old libraries is not recommended for
Once you successfully load the OpenSSL 0.9.6 libraries, you will likely encounter a secondary, more challenging hurdle: .
If your target server requires TLS 1.2, you cannot use native Indy 9 components. You have three paths forward: Step 2: Place the DLLs Indy 9 cannot
Here is the only reliable methodology to get Indy 9 loading SSL on Windows 10/11.
