A tool to extract certificate information from the host.

Installation

Prerequisites

  • NodeJS - v7.2.0 (current)

API Reference

cerius is an extremely simple command line tool to use.

-h & -p flags

Cerius can identify & extract certificate information for any hostname that is passed to it using the -h flag as described below.

By default the port number, if not specified is 443

$ cerius -www.google.com
 
//output
www.google.com Certificate Information
Issuer: US, Google Inc, Google Internet Authority G2
Subject: US, California, Mountain View, Google Inc, www.google.com
Subject Alternative Names: www.google.com
Expires on: 02/02/2017 in 2 months

If a different port needs to be specified, then the same can be done as in the below example

$ cerius -www.google.com -443
 
//output
www.google.com Certificate Information
Issuer: US, Google Inc, Google Internet Authority G2
Subject: US, California, Mountain View, Google Inc, www.google.com
Subject Alternative Names: www.google.com
Expires on: 02/02/2017 in 2 months

Bulk option

There are chances when certificate information is to be extracted for a list of servers. In that case we can use the bulk option, which accepts two parameters "path of the file to get list of servers" and "name of the output file". bulk option only supports Excel files at the moment.

Syntax: cerius bulk {path_to_file.xlsx} {output_file.xlsx}.

!!NOTE: when using bulk option, the output file will be generated in the current directory

The input excel file should have only one column filled with the host-names for which the information is to be extracted.

$ cerius bulk ./servers.xlsx certificates.xlsx
 
//output
100% processed - extracted certificate information for www.google.com [expires in 2 months] in 0.2s
 
Certificate analysis is complete.
