title: DSM7: Secure connection to Synology NAS in LAN (no letsencrypt)
body: <p>I know from <a href="https://jeangalea.com/setup-ssl-synology-nas/" rel="nofollow noreferrer">this page</a> that there should be a way to use self-signed certificates in my LAN in order to establish encrypted connections between my computers and my local synology NAS.</p>
  <p>In essence it says:</p>
  <blockquote>
  <p>It has two prerequisites:</p>
  <p>Your Diskstation must have a fixed IP address on your LAN. You must be
  able to add or assign certificates to devices you want to approve your
  SSL. If you can satisfy those conditions, proceed with the following
  steps:</p>
  <p>In DSM 6.0 -&gt; Control Panel -&gt; Security -&gt; Certificate</p>
  <p>Click “Add” to start the process and choose “Create self-signed
  certificate”</p>
  <p>First you create a Certificate Authority (CA) which is the master key
  that will sign the site usable SSL.</p>
  </blockquote>
  <p>However in my case (DSM 7.0-41890) I cannot see any options saying &quot;create self signed certificate&quot;</p>
  <p>Does anybody know how to do this with DSM 7?</p>
  <p>I don't need 100% security, I just want the communication between devices in my network to be encrypted. I don't want any malicious program in my network to be able to see passwords in clear text by just monitoring network traffic...</p>
