Nice backing and it looks legit.
I have been using SSL from http://www.startssl.com/ and you can see it here: https://www.sch.my/. May be I'll try your suggestion.
By the way, what is the conditions for using it (for free)?
It just works: https://letsencrypt.org/howitworks/
Looks like an interesting alternative for sure !
you can try wosign too: https://www.wosign.com/english/freeSSL.htm
I like wosign SSL if compared to letsencrypt SSL since it allows us to go free for a year instead of only 90 days.
