Then call:
The simplest approach is to copy libeay32.dll and ssleay32.dll directly into the same folder as your .exe file.
For development or advanced deployment, you may also place them in a system path folder, although placing them with the executable is the simplest and most common approach.
A: Your development machine likely has the OpenSSL DLLs in a system path (e.g., C:\Windows\System32 ), or the DLLs are present in your project's output folder. The client's machine does not have them. The fix is to include the DLLs with your application distribution as described in Step 5.
Suggest for Delphi 7 that support modern TLS. Help you find trustworthy, older DLL files . Delphi 7 Indy 9 Could Not Load Ssl Library
This report addresses the common runtime error encountered by developers using Delphi 7 and Indy 9 components (specifically TIdHTTP or TIdSMTP ) to establish secure connections. This issue typically arises when the application cannot locate or incompatible versions of the OpenSSL libraries ( libeay32.dll and ssleay32.dll ) required for SSL/TLS operations. The primary solution involves placing the correct DLL versions in the appropriate system directories.
Ensure your application can find the libraries:
Encountering the "Could Not Load SSL Library" error in Delphi 7 while using Indy 9 is a classic issue. It happens when your application tries to initiate a secure connection (HTTPS, FTPS, SMTPS) but cannot find or initialize the required OpenSSL dynamic link libraries (DLLs).
The "Could Not Load SSL Library" error is a classic hurdle for developers maintaining legacy Delphi 7 applications. This error occurs when the Indy 9 internet component suite cannot locate or initialize the required OpenSSL dynamic link libraries (DLLs) on the host system. Then call: The simplest approach is to copy libeay32
procedure TForm1.ForceIndySSL; var Path: string; begin Path := ExtractFilePath(Application.Exename) + 'openssl';
In the modern security landscape, almost all web servers, APIs, and mail providers have completely deprecated these protocols due to vulnerabilities like POODLE and BEAST. They now mandate .
By following this guide, you should be able to resolve the "Could not load SSL library" error in your legacy Delphi 7 application.
Alternatively, place them in C:\Windows\System32 (for 32-bit OS) or C:\Windows\SysWOW64 (for 64-bit OS), though application-local deployment is generally preferred. 3. Configuring TIdSSLIOHandlerSocket You must tell Indy 9 to use these libraries. The client's machine does not have them
The error in Delphi 7 with Indy 9 typically occurs because the specific version of OpenSSL DLLs required by the component is missing, incompatible, or inaccessible. 1. Core Problem: Version Incompatibility
For your Delphi 7 application to see the libraries, they must reside in a directory checked by the Windows library search order.
Indy 9 is deprecated, and OpenSSL 0.9.x/1.0.x has reached End of Life (EOL). Using these libraries exposes your application to known security vulnerabilities.
