Activate the option SSL on the tab Basic of the web and go to the tab SSL. Provide your information there (State/county and Organizational unit are optional”).
Please leave empty the fields SSL Request and SSL Certificate. Choose Create Certificate under Action and then click on Save.
Afterwards, if you go to the tab SSL again, you will find the Certificate Signing Request (CSR) under SSL Request. Copy the CSR. With this CSR you can apply for an SSL certificate at companies like Verisign (www.verisign.com), Baltimore (www.baltimore.com), Entrust (www.entrust.com), Geotrust (www.geotrust.com), IPSCA (www.ipsca.com) or InstantSSL (www.instantssl.com).
Follow the instructions given on the website of the respective company. (Some companies issue trial certificates.)
After you get your certificate, copy it into the field SSL Certificate and choose Save certificate under Action.
Please note: To secure a website with SSL, you do not have to apply for a certificate at the companies mentioned above. You then have to live with a warning message that pops up in a user’s browser as soon as they visit the website. This may be a little irritating.
