How to use OpenSSL for https requests?

Hi everyone,

I am connecting to a https endpoint using TWinHttp, but there is a ploblem in SSL handshake on an windows server 2012 system, which I believe is related to winhttp.dll available ciphers.

How can I connect to a HTTPS endpoint using OpenSSL and Mormot?

I was able to complete the request using Indy with OpenSSL, but I believe mormot to be more robust and most of my implementation is already using mormot.

Re: How to use OpenSSL for https requests?

Define USE_OPENSSL and FORCE_OPENSSL conditionals for your project.

Then you could use the socket client for HTTPS with no problem, e.g. via OpenHttp() from mormot.net.client.

Are those Mormot 2 exclusive conditionals?

I am using mormot 1.1 and could not find any source file that use them, or mormot.net.client.

Ah...

OpenSSL is supported only with mORMot 2.

On mORMot 1, you can use OpenSSL but with libcurl.

Oops, Arnaud was faster.

Under mORMot1 with cUrl. Define USELIBCURL. With function SynCrtSock.HttpGet.

With best regards
