That's some neat trick @emilmoe . Lately hearing some good things about Lets encrypt but still I'm too skeptical to go with it. Maybe I will start using it for my pet projects and later on use it in production apps. But, what do you think about it?
I'm am currently using it on my personal website www.emilmoe.com and 2 projects (non public). One of them has been active for 8 months the other just launched. The last one needed a proprietary single sign on, which means it had to be approved manually, Let's Encrypt was good enough for this.
As far as I have read the level of encryption is exactly as the known brands.
