Downloads are from a bit cryptic page [WayBack] Download the Free Nmap Security Scanner for Linux/Mac/Windows via [WayBack] Windows | Nmap Network Scanning.
An alternative is to go to [WayBack] nmap.org/dist, then search for the bottom most files having .exe or .zip extensions.
It is much more modern than netcat (see some links on that below) and has elaborate documentation:

Unwrap SSL
Suppose you need to connect to an IMAP server that requires SSL, but your mail reader doesn’t support SSL. Ncat can act as the encrypted bridge to connect the client and server. You will connect the mail client to a local port and Ncat will forward the traffic, encrypted, to the server. Here’s how to connect IMAP (port 143) on the local host to IMAP over SSL (port 993) on
imap.example.com.ncat -l localhost 143 –sh-exec “ncat –ssl imap.example.com 993”
