SSL Checker Script for SLACK

Overview

The SSL Checker script is a Bash script designed to check the SSL certificate expiration status for a list of domains and send notifications to Slack channels based on the remaining days until expiration. It utilizes WHOIS information and OpenSSL to retrieve SSL certificate details.

Features

• Checks SSL certificate expiration for multiple domains.
• Sends notifications to Slack channels with color-coded information and icons.
• Supports different Slack channels for each domain.

Before using the script, ensure the following prerequisites are met:

1. Bash shell environment.
2. dig, whois, openssl, and curl commands installed.
3. Incoming Webhooks integration enabled in your Slack workspace.
