TLS version

I use WinSCP on Windows 11 via batch file to access files on an AWS cloud server. Now I'm told I need to use TLS 1.2 or 1.3. Is the TLS version built into Windows, or is it built into WinSCP? How can I tell which version of TLS I'm using now?

Re: TLS version

WinSCP supports TLS up to 1.3.
It will automatically use the highest version that the server supports.
You can tell what version is actually used on Server and protocol information dialog:

Or in the session log file.
You can prevent WinSCP from ever using versions below TLS 1.2 in session settings:
