## Let's Encrypt { #lets-encrypt }

Before Let's Encrypt, these **HTTPS certificates** were sold by trusted third parties.

The process to acquire one of these certificates used to be cumbersome, require quite some paperwork and the certificates were quite expensive.

But then **[Let's Encrypt](https://letsencrypt.org/)** was created.

   * refer only to types present under Android, so we could implement them in {@code
   * TypeVariableImpl} today. (We could probably then make {@code TypeVariableImpl} implement {@code
   * AnnotatedElement} so that we get partial compile-time checking.)
   *
   * <p>This workaround should be removed at a distant future time when <a
   * href="https://issuetracker.google.com/issues/115932459">Android supports {@code
   * AnnotatedType}</a>.

   * compared. This comparator imposes a "partial ordering" over the type {@code T}. Subsequent

   * values in the list are not supported.
