+        When uploading a file to blek! File, you may add a password to it, if it has confidential data.
+    </p>
+
+    <p>
+        However, be aware that even though the file won't be sent unless the user provides a password,
+
+        <b>the instance owner will still be able to see the file contents without a password.</b>

+    <h2>Why can't the site encrypt it for me?</h2>
+    <p>
+        There is a number of reasons why that is a stupid idea.

+            This site's only purpose is to store files for short periods of time.
+            It doesnt include "storing the files securely", or encrypting them.
+        </li>
+        <li>
+            When the encryption happens server-side, there is a risk that the password could be logged.
+        </li>
+    </ol>
+
+    <h2>How do I encrypt a file, then?</h2>
+    <p>
+        Its dead simple: download a program for encrypting files on your computer and use it to handle
+        all encryption operations.
+    </p>
+    <p>
+        As for the encryption program, it is recommended to use
+        <a href='https://gnupg.org'>GnuPG</a>
+        (
+            <a href="https://gpg4win.org">Windows</a>

+            Kleopatra

+        is a cross-platform easy to use GUI for GPG.
