SSL Expiry Checker

The SSL Expiry Checker is a simple command-line tool written in Go that checks the expiry date of SSL certificates for a given target URL. It provides information about the remaining days until the SSL certificate expires.

Installation

Needs golang 1.20+ installed.

To use the ssl-expiry tool, you need to have Go installed on your system. If you haven't installed Go, you can download it from the official Go website: https://golang.org/dl/

Once you have Go installed, you can install the ssl-expiry tool using the following command:

go install github.com/usysrc/ssl-expiry@latest

Usage

Replace <targetURL> with the URL of the website whose SSL certificate you want to check. The tool will display the certificate expiry date and the remaining days until expiry.

Or without the schema and with a port:
