All linux hosting with CPanel that had not previously installed an SSL / TLS security certificate have been provided free of charge with a certificate issued by Let's Encrypt.
SSL certificates issued by Let's Encrypt will remain free and will automatically renew without user intervention.
This way it is possible to use https: // in the web, besides having data encryption in connections with the mail service, ftp and others.
Request your web hosting service with CPanel if you do not already have it.
