Purpose of the SSL Certficate Scanner Tool
Use this tool to scan a range or list of servers and
the SSL Certificates and connection levels (SSLv2, SSLv3, TLS1,
TLS1.1, TLS1.2 etc) supported by the
servers. Note: as of Jan 2019 Windows SCHANNEL does NOT
support TLS1.3, so we cannot test TLS 1.3 connections.
