Can you have 2 SSL certificates on one server?
You absolutely can use one SSL certificate for multiple domains — or one SSL certificate for multiple subdomains in addition to domains. For securing multiple domains with a single SSL certificate we use either a multi domain/UCC/SAN certificate or a multi domain wildcard SSL certificate.
Can you transfer SSL certificate to another server?
Because SSL certificates are tied to specific domain names, you cannot simply transfer an SSL certificate you registered with one domain name to a server for a different domain name. Even if you keep the same server but change domain names, the certificate will still not work.
Do SSL certificates apply to subdomains?
Yes, if you have only 2-3 subdomains, you can get a multi-domain SSL certificate. Here, you need to treat your subdomains as separate SAN.
How to export SSL certificates from one server to another?
Export the SSL certificate from the server with the private key and any intermediate certificates. Convert the certificate to a different format if you are putting it on a different type of server. Import the SSL certificates and private key on the new server and configure your sites to use them.
Why is it important to use SSL certificate?
A web browser reaching the server, and validates that an SSL server certificate is authentic. That tells the user that their interaction with the web site has no eavesdroppers and that the web site is exactly who it claims to be. This security is critical for electronic commerce, which is why certificates are now in such widespread use.
Can a certificate be used to sign another certificate?
Basically I want to use one certificate that is signed for the domain and create new certificates for subdomains using domain certificate as CA for the subdomains. How is this process designed to work? Whether or not a certificate can be used to sign another certificate is defined by the basic constraints field of the certificate.
Do you need a server license to install a SSL certificate?
Keep in mind that some certificate authorities, require that you purchase a ” server license ” for each server that you install an SSL certificate to, even if it uses the same private key. And speaking of private keys, it is slightly less secure to copy the SSL certificate and use the same private key on a different server.
