This script checks the expiry dates of a domain and SSL certificate in days. It uses whois and openssl commands to retrieve the expiry dates from google.com.br and a local .pem certificate file. The dates are converted to timestamps and subtracted from the current date to calculate the number of days until expiry, which is printed out.
