Delphi 7 Indy 9 Could Not Load Ssl Library -

If your application needs to talk to modern HTTPS servers, consider these structural alternatives: Upgrade to Indy 10

Recommended OpenSSL builds for Indy 9 + Delphi 7

Here is a quick reference for common code changes and component assignments:

Ensure you are using OpenSSL 0.9.6 binaries, not 1.0.x or 1.1.x. Missing Dependencies Some DLL builds require the Visual C++ Redistributable Delphi 7 Indy 9 Could Not Load Ssl Library

If you see “1.0.2u”, you are on the right track.

⚠️ Critical Limitations of Indy 9 in Modern Environments

HTTP.IOHandler := SSL; HTTP.HandleRedirects := True; If your application needs to talk to modern

Indy components are designed to support SSL/TLS encryption, but they don't include the core cryptographic libraries themselves. A separate, external library is required to perform the handshake and encryption. In Indy's architecture, this functionality is delegated to the OpenSSL library, which Indy loads dynamically at runtime as two DLL files: libeay32.dll and ssleay32.dll .

: Indy 9 generally requires OpenSSL 0.9.6 DLLs. Modern versions of these DLLs lack specific functions (e.g., exports ending in _indy ) that Indy 9 expects.

OpenSSL 0.9.6 only supports .In the modern security landscape, practically all modern web servers, APIs, and mail providers (like Google, Microsoft, and Cloudflare) have completely deprecated SSLv3 and TLS 1.0 due to severe vulnerabilities (such as POODLE and BEAST). Modern servers strictly require TLS 1.2 or TLS 1.3 . A separate, external library is required to perform

The DLLs do not support TLS 1.2/1.3, which is required by the server you are connecting to. 2. The Solution: Updating OpenSSL DLLs
