Switching my SSL certificates to Let's Encrypt

Today I switched my sites from StartSSL to Let's Encrypt. It took about 5 minutes.

Despite its’ quirky user-interface StartSSL has served me well, but it’s time to move on to an even more convienient service: Let’s Encrypt

I received my Let’s encrypt beta program invitation e-mail last week (only shortly after signing up for the beta program). And now I took the very simple steps described in the e-mail to create my first SSL certificates signed by Let’s Encrypt.

And there the result. “https://andykdocs.de" before and after:

Steps for creating Let’s Encrypt SSL certificates

  1. Connect to the server that will run your websites
  2. Clone the Let’s Encrypt Client

    cd /usr/local/src
    git clone https://github.com/letsencrypt/letsencrypt
    
  3. Start the Let’s Encrypt dialog (letsencrypt-auto)

    cd /usr/local/src/letsencrypt
    ./letsencrypt-auto --agree-dev-preview --server \
        https://acme-v01.api.letsencrypt.org/directory certonly
    
  4. The first time you will be prompted to enter an E-Mail address.

  5. Then you only have to enter the domain names you want to create SSL certificates for.

The created SSL certificates will be stored in /etc/letsencrypt/live/:
