# Use a custom certificate
|
|
|
|
By default, Zulip generates a signed certificate during the server install
|
|
process. In some cases, a server administrator may choose not to use that
|
|
feature, in which case your Zulip server may be using a self-signed
|
|
certificate. This is most common for Zulip servers not connected to the
|
|
public internet.
|
|
|
|
## Web
|
|
|
|
Most browsers will show a warning if you try to connect to a Zulip server
|
|
with a self-signed certificate.
|
|
|
|
If you are absolutely, 100% sure that the Zulip server you are connecting to
|
|
is supposed to have a self-signed certificate, click through the warnings
|
|
and follow the instructions on-screen.
|
|
|
|
If you are less than 100% sure, contact your server
|
|
administrator. Accepting a malicious self-signed certificate would
|
|
give a stranger full access to your Zulip account, including your
|
|
username and password.
|
|
|
|
## Desktop
|
|
|
|
### Version 5.4.0 and above
|
|
|
|
Zulip Desktop version 5.4.0 and above use the operating system's
|
|
certificate store, like your web browser.
|
|
|
|
{start_tabs}
|
|
{tab|mac}
|
|
1. Hit Cmd+Space to bring up Spotlight Search, type **Keychain
|
|
Access**, and press Enter.
|
|
|
|
2. From the **File** menu, choose **Import Items...**
|
|
|
|
3. Navigate to the certificate file, then click **Open**.
|
|
|
|
4. Right-click the newly-added certificate, and click **Get Info** from
|
|
the context menu.
|
|
|
|
5. Expand the **Trust** section.
|
|
|
|
6. Select **Always Trust** for the **Secure Sockets Layer (SSL)** option.
|
|
|
|
7. Close the window. You will be prompted for your password to verify
|
|
the change.
|
|
|
|
8. Restart the Zulip Desktop application.
|
|
|
|
{tab|windows}
|
|
On Windows, Zulip Desktop shares the certificate store with
|
|
Google Chrome, so you can add certificates to it from inside
|
|
Chrome.
|
|
|
|
1. Open Google Chrome.
|
|
|
|
2. From the Chrome menu (⋮) in the top-right, select **Settings**.
|
|
|
|
2. In the **Privacy and Security** section, click **Security**.
|
|
|
|
3. Scroll down to and click **Manage Certificates**.
|
|
|
|
4. Select the **Trusted Root Certification Authorities** tab.
|
|
|
|
5. Select **Import...**
|
|
|
|
6. Navigate to the certificate file, then click **Open**.
|
|
|
|
7. Select **Done**.
|
|
|
|
8. Restart the Zulip Desktop application.
|
|
|
|
{tab|linux}
|
|
The required packages and steps vary by distribution; see the Chromium
|
|
documentation for [detailed documentation][linux]. On most systems,
|
|
once the `nss` tools are installed, the command to trust the
|
|
certificate is:
|
|
|
|
```
|
|
certutil -d sql:$HOME/.pki/nssdb -A -t "C,," -n zulip \
|
|
-i path/to/certificate.pem
|
|
```
|
|
|
|
You will need to restart the Zulip Desktop application to pick up the
|
|
new certificate.
|
|
{end_tabs}
|
|
|
|
|
|
### Version 5.3.0 and below
|
|
|
|
On Zulip Desktop version 5.3.0 and below, we require you to manually
|
|
enter the certificate details before you can connect to your Zulip
|
|
server. You'll need to get a certificate file (should end in `.crt` or
|
|
`.pem`) from your server administrator and add it:
|
|
|
|
{start_tabs}
|
|
|
|
1. Click on the **gear** (<i class="fa fa-cog"></i>) icon in the lower left corner.
|
|
|
|
2. Select the **Organizations** tab.
|
|
|
|
3. Under **Add Custom Certificates**, enter your organization URL and add
|
|
the custom certificate file (it should end in `.crt` or `.pem`).
