Do you know when your domains and SSL certificates expire?

• Install dependencies by running composer install.
• Update the array of domains in the ./config.php file.
• Run the checks using the command below.

The following command will check each domains whois expiration, and if applicable the certificate expiration.

php -f ./check.php

Note: By default whois and certificate data is cached for 24 hours.

Downloading domain certificates uses the local openssl s_client command.

Reading the downloaded certificates also uses the openssl_x509_parse function which means PHP should be compiled with the --with-openssl flag.
