Will Let's Encrypt work on Hostmonster?


I read the FAQs here and on certbot, nothing about Hostmonster.
I Googled “letsencrypt hostmonster” and “certbot hostmonster” and nothing.
I’ve searched Hostmonster help and nothing on letsencrypt or certbot.

In the drop down list for operating systems on certbot, the only linux is “Arch Linux”, however in my cpanel on hostmonster, it says the operating system is “Linux”. So, I do not know if it would be safe to select “Arch Linux” on certbot.

The help on hostmonster says one must have a dedicated IP address to install SSL/TLS. However, reading on the topic here, it is clearly stated that dedicated IP addresses are no longer needed.

So, I have these questions:

  1. Has anyone gotten a Let’s Encrypt certificate on their Hostmonster account and if so, how did you do it?

  2. Do I need a dedicated IP address to get a Let’s Encrypt certificate?

  3. What do I choose for the operating system on certbot?

  4. I have a main domain “MainDomain.com” and another domain “OtherDomain.com” where “OtherDomain.com” maps to “OtherDomain.MainDomain.com” as a sub domain. I want a certificate for both domains, will a certificate for “MainDomain.com” also cover “OtherDomain.com” or will I need to get another certificate for “OtherDomain.com” as well?

Thank you for your help.

  1. Not me, so no idea :slight_smile:

  2. It is possible to host multiple sites on one IP thanks to SNI (Server Name Indication), though some clients not supporting that might fail to connect - see https://en.wikipedia.org/wiki/Server_Name_Indication#Support

However, your particular hoster might require a client to buy a dedicated IP, which seems to be the case here - https://my.hostmonster.com/cgi/help/473

  1. I believe that as long as it is some Linux, it should work, but better stick to a list given on https://certbot.eff.org/

  2. You can include up to 100 domain names on the same certificate if you like.
