Proton C++ with OpenSSl on Windows

[Stefan Hoelzer <st...@deutsche-boerse.com.INVALID>]

Hi,
Is it possible to use the Proton C++ API with openSSL on Windows?
If yes how?

If I run cmake to build the proton library I get:

D:\qpid-proton-0.39.0\build>cmake ..
-- Building for: Visual Studio 17 2022
-- Selecting Windows SDK version 10.0.22621.0 to target Windows 10.0.14393.
-- The C compiler identification is MSVC 19.37.32825.0
-- Detecting C compiler ABI info
-- Detecting C compiler ABI info - done
-- Check for working C compiler: C:/Program Files/Microsoft Visual Studio/2022/Professional/VC/Tools/MSVC/14.37.32822/bin/Hostx64/x64/cl.exe - skipped
-- Detecting C compile features
-- Detecting C compile features - done
-- Found OpenSSL: optimized;C:/Program Files/OpenSSL-Win64/lib/VC/libcrypto64MD.lib;debug;C:/Program Files/OpenSSL-Win64/lib/VC/libcrypto64MDd.lib (found version "3.0.8")
...

If I run the ssl_client_cert.cpp example, it selects per default the .p12 files and it works as expected.

if I manipulate the using_OpenSSL()function to return always true here,  the example application using the .pem files but I get:

SSL certificate initialization failure for ssl-certs/tserver-certificate.pem:ssl-certs/tserver-private-key.pem:tserverpw

My application target is x64.
But _WIN32 as well as _WIN64 is defined per Compiler default.

I need openSSL here to support TLS v1.3 and it works fine for other libraries like for example nats.

Any Idea?

Many thanks
Stefan
