## Let's Encrypt

Vor Let's Encrypt wurden diese **HTTPS-Zertifikate** von vertrauenswürdigen Dritten verkauft.

Der Prozess zum Erwerb eines dieser Zertifikate war früher umständlich, erforderte viel Papierarbeit und die Zertifikate waren ziemlich teuer.

Aber dann wurde **<a href="https://letsencrypt.org/" class="external-link" target="_blank">Let's Encrypt</a>** geschaffen.
