Plesk control panel has its own SSL certificate, signed by Plesk, but most browsers do not recognize it as valid.
If you want to secure your Plesk control panel from a valid and recognized C.A. (Certification Authority):
- Login in Plesk with admin role
- Go to Tools & Settings => Security => SSL Certificates . A list of SSL certificates that you have in your repository will be displayed.
- Click Add
- Specify the certificate properties:
– certificate name (a mnemonic to identify your certificate in the repository)
– Encryption level (choose 2048 bit)
– Specify your location and organization name (max 64 characters)
– specify the hostname of your Plesk installation
– specify your email address
- double-check all the information you provided, because depending on the kind of your SSL certificate (DV, OV or EV) this information will be included or not in your certificate
- click Request
Plesk will generate your private key and CSR (Certificate Signing Request) and store them in the repository
- click the name of the certificate you need; a page with the certificate’s properties will open.
- Locate the CSR section, and copy to the clipboard all the text (including “—–BEGIN CERTIFICATE REQUEST—–” at the beginning and “—–END CERTIFICATE REQUEST—–” at the end
- order your SSL certificate on euroSSL
(What kind of SSL certificate? We suggest you a cheap DV SSL Certificate, or a most professional and widely recognized OV SSL Certificate. Usually, a much more expensive EV SSL Certificate is not worthwhile for such kind of application.)
- When you receive your new SSL certificate, return to Plesk’s SSL Certificates Repository, select your certificate and click Upload Certificate
- Copy and paste in plain text the certificate (.crt) and the CA certificate (-ca.crt) which were provided to you together, and then click Upload certificate
- Once you have uploaded your new certificate to the repository, select the corresponding checkbox and then click Secure Plesk
It’s all: now your Plesk is secured by the new certificate, and the green closed lock will appear in the navigation bar of the browser.
