If you visit https://www.startssl.com/ you can get a 256-bit SSL, and the public string can be as strong as 4,096-bits (which is the highest available on modern browsers). Their website is a hassle to browse, but they are providing a completely free SSL that's super secure and always free to renew. You should secure logins on the site. @shoghicp It's also 100% free.
CloudFlare gives free SSL and if you try to connect the site with HTTPS, it will work. The only issue is the elements on the site aren't loaded as HTTPS (even though they have the ability to be).
