Project Description:
Using VBA in Excel, I need to be able to make an HTTPS POST request to a server.
Please note: I can already make a HTTP POST request using this code:

Set web = New WinHttpRequest
Const WinHttpRequestOption_EnableRedirects = 6
web.Option(WinHttpRequestOption_EnableRedirects) = True
web.Open "POST", url, True
web.SetRequestHeader "Content-Type", "application/x-www-form-urlencoded"
web.Send "mydata=" & data

What I need is to be able to make an HTTPS request, i.e. with encryption.
I tried using "web.SetClientCertificate" to specify a certificate for HTTPS, but was unable to make it work.
Please provide a working sample on how to make an HTTPS POST request in VBA.
Note: you don't need to use WinHttpRequest, that's just what I tried.
Please use any method which does the job, and provide a working sample plus installation instructions (if an external library such as CURL is needed, for example).
