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

До появления Let's Encrypt эти **HTTPS-сертификаты** продавались доверенными третьими сторонами.

Процесс получения таких сертификатов был неудобным, требовал бумажной волокиты, а сами сертификаты были довольно дорогими.

Затем появился **<a href="https://letsencrypt.org/" class="external-link" target="_blank">Let's Encrypt</a>**.

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.

Antes de Let's Encrypt, esses certificados HTTPS eram vendidos por terceiros confiáveis.

O processo de aquisição de um desses certificados costumava ser complicado, exigia bastante papelada e os certificados eram bastante caros.

Mas então o <a href="https://letsencrypt.org/" class="external-link" target="_blank">Let's Encrypt</a> foi criado.
