Purpose of the SSL Certficate Scanner Tool

Use this tool to scan a range or list of servers and retrieve the SSL Certificates and connection levels (SSLv2, SSLv3, TLS1, TLS1.1, TLS1.2 etc) supported by the servers. SSLv2 and SSLv3 may not be available for testing due to operating system limitations. Note: as of Aug 2020 Windows SCHANNEL does NOT support TLS1.3, so we cannot test TLS 1.3 connections.

About the SSL Certificate Scanner Tool

The SSL Certificate Scanner Tool is used to quickly retrieve and check expiration dates and other parameters of SSL Certificates from a set of secure web servers. It also checks the web server itself to see if weak SSLv2/SSLv3 (if your OS allows this) connections are accepted. The tool is launched from within NetScanTools Pro and runs separately. It accepts a list of secure website hostnames or IPv4 addresses. Does not yet support TLS1.3.

How the SSL Certificate Scanner Tool works

It makes SSL connections to the target server.
It contacts each of the targets using different SSL levels, then retrieves the SSL certificate. The responses are displayed. You can then right click in the results and print, copy or export the results.

IPv6 targets will be supported in the future.
