Add-in Let'sEncrypt from customers domains

I need help adding and implementing this plugin: [login to view URL] (or similar that will work) Here's the current situation... Right now my customers are able to add their own whitelabel domains, so that rather than them seeing [login to view URL] they use a custom CNAME DNS entry on their website to have [login to view URL] map to [login to view URL] so that their customers never see [login to view URL] The only problem right now is that SSL isn't supported because when they try [login to view URL] it pulls from the wildcard SSL certificate on our website: *.[login to view URL] SSL certificate does not match the domain... So here's what we need, we need a way for the customer to provision their own SSL certificate when they add the whitelabel domain to their account. We need it to contact Let'sEncrypt to create the SSL certificate, install it on our dedicated server, and then auto-renew so that it doesn't expire. Once you have the script up and running in PHP 5.3 I can then take what you've done and then hook it into the existing scripts to be fired off when they add the custom domain!
