As of LiteSpeed Web Server v5.2, self-signed SSL certificates are automatically created for the Web Admin GUI.
However, if you have an older version of LSWS, a different self-signed certificate is wanted, or a non-self-signed certificate is needed then you can follow this tutorial: https://www.litespeedtech.com/support/wiki/doku.php/litespeed_wiki:config:admin-ssl?s[]=ssl&s[]=webadmin
If you still have questions about your SSL certificates, make sure to visit our SSL Certificates page or contact us by opening a support ticket or by using our live chat feature.
