Avant Let's Encrypt, ces **certificats HTTPS** étaient vendus par des tiers de confiance.

Le processus d'acquisition de l'un de ces certificats était auparavant lourd, nécessitait pas mal de paperasses et les certificats étaient assez chers.

Mais ensuite, **[Let's Encrypt](https://letsencrypt.org/)** a été créé.
