Certo - An SSL Certificate Checker

Certo checks one or several servers' SSL certificates for validity and impending expiration. It is made to be called regularly by a CRON job or CI system such as Jenkins and polls hostnames for SSL Certificates on port 443 and reports on their status :

• Certificate is valid
• Certificate is valid, but expires soon (configurable)
• Certificate could not be validated

TODO

• Support for custom CAs
• Example CRON/Jenkins jobs
• Async checks
