In my Delphi (10.3 community edition) program, I try to use Indy with the OpenSSL library, but I receive an error
Could not load SSL library
My OpenSSL library is version 1.0.2u and I put the libeay32.dll and ssleay32.dll files in my program EXE directory, and in Windows\SYSWOW64 and Windows\System32.
I have installed the Embarcadero Delphi Patch RS1033_Indy_SSL_Patch.
After the exception, I call WhichFailedToLoad() and the result is
Failed to load libeay32.dll
This is a simple program that raises the exception:
url := 'https://www.google.it';
try
Web := TIdHTTP.Create(nil);
hIOHand := TIdSSLIOHandlerSocketOpenSSL.Create(nil);
hIOHand.SSLOptions.SSLVersions := [sslvTLSv1,sslvTLSv1_1,sslvTLSv1_2,sslvSSLv23];
Web.IOHandler := hIOHand;
Web.Request.UserAgent := INET_USERAGENT; //Custom user agent string
Web.RedirectMaximum := INET_REDIRECT_MAX; //Maximum redirects
Web.HandleRedirects := INET_REDIRECT_MAX <> 0; //Handle redirects
Web.ReadTimeOut := INET_TIMEOUT_SECS * 1000; //Read timeout msec
try
Sito := Web.Get(Url);
Sito := DateToStr(Web.Response.LastModified) + Sito;
except
on e : exception do
stg := WhichFailedToLoad();
end;
finally
Web.Free;
end;
Can you help me to solve the problem?
I put the
libeay32.dllandssleay32.dllfiles in my program EXE directory
That is fine. That is the 1st place the OS will look for them.
and in
Windows\SYSWOW64and inWindows\System32
Don't do that! Non-system files do not belong there. ESPECIALLY if you are putting the same files in both folders, since Windows\SYSWOW64 is meant only for 32bit files and Windows\System32 is meant only for 64bit files.
Failed to load libeay32.dll
That means Windows could not load that DLL into memory at all. Probably because it couldn't find the dependent ssleay32.dll file, but more likely because you mixed up the 32bit and 64bit versions of the DLLs. If your app is compiled as a 32bit EXE, you must use the 32bit version of both DLLs. If your app is compiled as a 64bit EXE, you must use the 64bit version of both DLLs.
