I noticed that the last version of Lazarus (2.0.12) installs an old version of the OpenSSL Windows libraries (libeay32.dll / ssleay32.dll):
    DLL version: 1.0.2.10
    OpenSSL corresponding version: 1.0.2j
    Release year: 2016

The last available version of these dll files I could find (https://github.com/IndySockets/OpenSSL-Binaries) is:
    DLL version: 1.0.2.21
    OpenSSL corresponding version: 1.0.2u
    Release year: 2019

Is there a reason for this?

I am asking this also because I have an FPC program that uses the following version:
    DLL version: 1.0.2.16
    OpenSSL corresponding version: 1.0.2p
    Release year: 2018
This program -using this version- have been working perfectly on many Windows computers, but it wasn't able to make https connections on a specific Windows 10 Pro.
I fixed the problem by downgrading the dll files to version 1.0.2.10 which is the one installed by Lazarus!

Is it a known issue?
Is that why Lazarus still installs version 1.0.2.10 of these dll files?

Hi,
I have a similar issue.
Any tip from the developer team?

You can forget about OpenSSL DLLS and use Windows native wininet for web retrieval instead.
Lazarus 2.3, FPC 3.3.1 macOS 12.3.1 x86_64 Xcode 13.4
Lazarus 2.3, FPC 3.3.1 macOS 12.3.1 aarch64 Xcode 13.4

I didn't know about the "WinInet way", thanks!

But how do you handle a HTTPS POST connection with WinInet?
In other words, how can you get a similar behavior to TFPHTTPClient.FormPost(const URL: string; FormData: TStrings): RawByteString; ?

Can you give an example?

I'm more of a macOS user, but had to come up with a way to do it in Windows without the OpenSSL DLL hell. As for using post, my first Google result yielded: https://stackoverflow.com/questions/1823542/how-to-send-a-http-post-request-in-delphi-using-wininet-api
