TidHTTP [SSL], SSL errors is production, not in developement

mvanrijnen · July 14, 2022

* Same executing code

* Made sure i have the same OpenSSL Dll's

* Made sure calling the same URL

In production i get the following exception:


EIdOSSLUnderlyingCryptoError : Error connecting with SSL.
error:1408E0F4:SSL routines:SSL3_GET_MESSAGE:unexpected message

In the development environment it works perfectly (ofcourse 🙂 ).

Anyone any idea, what could be the problem here ?

My code for creating the idhttp component:

procedure THSJSonApiClient.InitHTTP;
begin
  fhttp := TIdHTTP.Create(nil);

  if UseSSL then
  begin
    fopenssl := TIdSSLIOHandlerSocketOpenSSL.Create(nil);
    //fopenssl.SSLOptions.Method := sslvSSLv23;
    fopenssl.SSLOptions.VerifyMode := [];
    fopenssl.SSLOptions.VerifyDepth := 0;
    fopenssl.SSLOptions.SSLVersions := [sslvTLSv1_2, sslvTLSv1_1, sslvTLSv1];
    fopenssl.PassThrough := False;
    fhttp.IOHandler := fopenssl;
  end;
  fhttp.handleredirects := True;

 

{$IFDEF DEBUG}
  flog := TIdLogEvent.Create(nil);
  flog.ReplaceCRLF := False;
  flog.LogTime := False;
  flog.Active := True;
  flog.OnReceived := CatchLogReceived;
  flog.OnSent := CatchLogSent;
  flog.OnStatus := CatchLogStatus;
  fhttp.Intercept := flog;
{$ENDIF}
end;

...location of the dll?

Yes, that differs, in the production environment they are next to the executable (checked it with process explorer), in development they are in a folder which is in the Path var.

(gonna check again now 🙂 , to be sure)

Big difference is the firewall,, production has a corporate Bitdefender installed, where on development we are on std Windows Defender (Windows 11)

Bitdefender installed

...why? 🤢 (only my opinion)

It's not my decision, but why not ? 😉

(It's AV/Malware/Randsomware protection)

but why not

i had problems with this...Windows Defender is imho good and enough...

...but now back to the topic.

Try to connect with openssl only like advised here https://github.com/openssl/openssl/issues/17386

Probably corp FW intercepts your TLS?

ok, on the same machine, i get (from the commandline) the following:

Command:

Okay, so we're sure this is not an issue on the openSSL=>network=>server part of chain. Remy your turn 🙂

Too make things more difficult, the exception is not always occuring in the production environment.

In the service there are two ways the method which goes wrong is called,

* Automaticly, every day around 18.30, from a seperate thread (cleanup thread)

* By hand, called from a client which throws a request in a queue, which is sequelly handled by the service

and now i'm typing this, i maybe realsie, that the ApiClient class, is used by mainclass of the service itself, as in the cleanup thread.

~~Could this somehow get in the way?~~ Yes, it can, stupid me 🙂 i see it now.

Which version of the DLLs are you using, though? TIdSSLIOHandlerSocketOpenSSL supports OpenSSL 1.0.2 or earlier. If you are trying to use OpenSSL 1.1.x or later, you need to use this SSLIOHandler instead: https://github.com/IndySockets/Indy/pulls/299

Quote

My code for creating the idhttp component:

The only issue I see with that code is you are creating the SSLIOHandler conditionally. You don't need to do that, you can access non-secure HTTP urls even with the SSLIOHandler assigned. TIdHTTP will handle the underlying TCP connection and SSLIOHandler.PassThrough property for you on a per-request basis, (re)connecting and toggling between TLS/non-TLS as needed. Because of that management, when you do create the SSLIOHandler, you don't need to set its PassThrough property manually at all.

The SSLIOHandler will also handle loading the OpenSSL DLLs dynamically only when they are actually needed, so if you never request an HTTPS url then the DLLs won't ever get loaded, and PassThrough will always be True.

So, I would suggest just getting rid of your UseSSL config option altogether, it is really not necessary. In fact, it will actually cause a runtime error if it is set to False and then you request a non-secure HTTP url that redirects to a secure HTTPS url. So, best to just have the SSLIOHandler assigned unconditionally instead, so it is always ready to go in case it is needed.

procedure THSJSonApiClient.InitHTTP;
begin
  fhttp := TIdHTTP.Create(nil);

  fopenssl := TIdSSLIOHandlerSocketOpenSSL.Create(fhttp);
  fopenssl.SSLOptions.VerifyMode := [];
  fopenssl.SSLOptions.VerifyDepth := 0;
  fopenssl.SSLOptions.SSLVersions := [sslvTLSv1_2, sslvTLSv1_1, sslvTLSv1];
  fhttp.IOHandler := fopenssl;

  fhttp.handleredirects := True;

{$IFDEF DEBUG}
  flog := TIdLogEvent.Create(nil);
  flog.ReplaceCRLF := False;
  flog.LogTime := False;
  flog.Active := True;
  flog.OnReceived := CatchLogReceived;
  flog.OnSent := CatchLogSent;
  flog.OnStatus := CatchLogStatus;
  fhttp.Intercept := flog;
{$ENDIF}
end;
