I've just wired you the amount needed to buy an SSL certificate from any of multiple reputable and well-priced providers. You can use the money I sent you to buy a cert from https://letsencrypt.org/ , https://www.startssl.com/Support?v=1 , or https://www.cloudflare.com/plans/ .

If those options aren't enough for you, let me know why and also how to non-vacuously send you money, and I'm happy to buy you a $4.99/year certificate from https://www.ssls.com/ssl-certificates/comodo-positivessl .
