git config - choosing https transport backend

[Wojciech Lewandowski]

Hi,
i would like to change "use the openSSL library" to "use the native windows secure channel library" after git installation.
Is it possible ? Do you know how to change that ?

I will be grateful for helping me solve this without reinstalling git on users notebooks.

Yes, it is possible, and you can find out how exactly it is done by
inspecting the source code for the installer, which is at
https://github.com/git-for-windows/build-extra in the
installer/install.iss file (this file is also easily found by a `git grep
"Secure Channel"`).

The relevant part is when the installer tests for the GC_WinSSL option to
do more interesting stuff than recording the user's choice:

if RdbCurlVariant[GC_WinSSL].Checked and (not
ReplaceFile(BinDir+'curl-winssl\curl.exe',BinDir+'curl.exe') or not
ReplaceFile(BinDir+'curl-winssl\libcurl-4.dll',BinDir+'libcurl-4.dll'))
then begin
Log('Line {#__LINE__}: Replacing curl-openssl with curl-winssl failed.');
end;

(See
https://github.com/git-for-windows/build-extra/blob/97c8294b584ae4b99059a1194a5eba24ee2ff1ab/installer/install.iss#L1774)

In other words, the installer will simply try to replace the curl.exe and
libcurl-4.dll files in <Git>\mingw64\bin (or the 32-bit equivalent) by the
files in <Git>\mingw64\curl-winssl\.
