## Let's Encrypt { #lets-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.

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

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.

import jcifs.smb1.util.LogStream;

/**
 * This servlet Filter can be used to negotiate password hashes with
 * MSIE clients using NTLM SSP. This is similar to {@code Authentication:
 * BASIC} but weakly encrypted and without requiring the user to re-supply
 * authentication credentials.
 * <p>
 * Read <a href="../../../ntlmhttpauth.html">jCIFS NTLM HTTP Authentication and the Network Explorer Servlet</a> for complete details.
