Server Certificate FAQs
- Enable encrypted data transfer for users accessing HTTPS, or other SSL enabled services on your server
- Authenticate your server to Clients accessing those servers.
CAcert only issues certificates for publicly registered DNS domains, it's not possible to get certificates for IP adresses or internal domains (like xxx.local, read FAQ/NoDomainName for further explanations).
You must be able to confirm that you are the owner (or authorized administrator) of the domain by responding to a 'ping' email sent to either the email address listed in the whois record, or one of the RFC-mandatory addresses (hostmaster/postmaster/etc). Please see FAQ/DomainOwner
- Certificates expires in 6 months for unassured accounts; 24 months for assured accounts.
Only the domain name itself can be entered into the certificates (not your full name, company name, location, etc.). To get more information into the certificate you may consider an OrganisationAssurance.
