• Sends notifications via WeChat Work (企业微信) when certificates are close to expiration
• Configurable through simple text files
• Designed to run as a cron job on Linux systems

Requirements

• Python 3.8+
• Poetry for dependency management

   git clone https://github.com/rtmax0/ssl-daily-check.git
   cd ssl-checker
   

2. Install dependencies using Poetry:

Configuration

1. Create a ~/.ssl-daily-check/domains.txt file with the domains you want to monitor:

   example.com:Example Website
   yourdomain.com:Your Website
   

2. Create a ~/.ssl-daily-check/notify-rule.json file with your WeChat Work webhook URL:

   [
     {
       "id": "notify1",
