Manually install an SSL certificate on your instance

It is possible to install SSL certificates manually on your Simple Hosting instance. For automatic installation please see this page in our documentation.


An SSL certificate lets you protect a website, or multiple addresses in the case of Wildcard and Multi-Domain certificates. Click here for more information on the various types of our SSL certificates.

It is possible to install Gandi SSL certificates on your simple hosting instance if:

In this case, you can proceed by going to your instance’s management page, specifically the page of the site that you want to protect, then:

  1. Click on “Upload an SSL Certificate**” to go to the “Upload Certificate” interface.
  2. Paste your certificate in the “SSL Certificate” field (not the CST, you must paste the CRT). Note that the first line of an SSL certificate created by OpenSSL begins with %%—–BEGIN CERTIFICATE—–%%. All the lines must be run together and please be sure that there are no line breaks at the end of of the form.
  3. Paste your private key in the “Key” field. The private key must be kept strictly confidential and must not be divulged to anyone. That would render the certificate useless. It is stored in an encrypted manner at Gandi once you have added it to an instance and the website’s connection is secured.
  4. click on “Create” to finish the process. If the certificate/private key pair corresponds to the domain to protect, then the operation will be successful.

If you install a “Wildcard” or “Multi-domain” SSL certificate, you will only need to install it once, on one of the valid addresses: all the other addresses in question will be protected.
