Let's Encrypt with Nginx

Here's how I set up a tiny Nginx/Rails server that uses HTTPS via a Let's Encrypt issued certificate.

https://letsencrypt.paddd.de/

Server

I use the smallest DigitalOcean droplet (512 MB) here, which is built from the "Ubuntu Ruby on Rails on 14.04" image provided by them.

Configuring nginx for SSL SNI vhosts

Gotchas

• Note that SHA2 hash algorithm may be not supported on older systems (Windows XP, Windows 2003, among others).
• Be aware that mandatory https on SNI vhosts eliminate [Internet Explorer on Windows XP, among others] (http://en.wikipedia.org/wiki/Server_Name_Indication#Web_browsers.5B6.5D).

Remarks

• My version of konklones SSL config does not have SPDY support(my nginx+openssl does not support it)
• You need a default ssl server (example.org-default.conf).
• Some SSL-options have to be unique across your instance, so it's easier to have them in a common file(ssl.conf).

# Generate a new pgp key: (better to use gpg2 instead of gpg in all below commands)
gpg --gen-key
# maybe you need some random work in your OS to generate a key. so run this command: `find ./* /home/username -type d | xargs grep some_random_string > /dev/null`

# check current keys:
gpg --list-secret-keys --keyid-format LONG

# See your gpg public key:
gpg --armor --export YOUR_KEY_ID
# YOUR_KEY_ID is the hash in front of `sec` in previous command. (for example sec 4096R/234FAA343232333 => key id is: 234FAA343232333)
