Cert-Check

Cert-Checker is a simple and efficient Go application that helps you monitor SSL/TLS certificates for specified domains. It checks the validity of certificates at regular intervals and logs certificate failures. It also optionally supports logging to Papertrail.

Installation

Pre-Built Binaries

You can download the latest release from the releases page.

Building from Source

Alternatively, you can build the application from source:

git clone https://github.com/peteretelej/cert-checker.git
cd cert-checker
go build

# run app
./cert-checker -domain example.com -interval 1m

Usage

You can run the app using the following command-line options:

Usage of cert-check:
  -domain string
        domain to validate
  -domains string
        text file contain domains to validate, see sample (optional)
  -interval duration
        interval to validate domain (optional, default 30s) (default 30s)
  -papertrail string
        papertrail destination address logsN.papertrailapp.com:XXXXX (optional)

Example

./cert-check -domain example.com -interval 1m -papertrail papertrail.example.com:12345

This command will check the SSL/TLS certificates for example.com every minute and send the logs to the specified Papertrail destination (if provided).

Replace example.com with the domain you want to check, 30s with the desired check interval (e.g., 1m for one minute,1h etc), and (If you want to log to papertrail) papertrail.example.com:12345 with your Papertrail logging address and port.
