Check the certificates' expiration date
Here are Bash and PowerShell scripts that check the expiration dates of certificates in a Java keystore and notify you about certificates that are either expired or will expire in less than 30 days:
...
Replace /path/to/your/keystore.jks with the actual path to your Java keystore file and your_keystore_password with your keystore password. Set appropriate permissions on the script file and execute it in a proper environment.
Please note that this script assumes that the keytool command is available in your environment (usually comes with Java installations). Also, ensure that you have the necessary permissions to access the keystore file.
