Can I have two certificates?

There's no mechanism that would stop you from issuing multiple certificates for the same domain. In fact, that's what you do every time you renew your SSL certificate — you issue a new certificate while the old one is still active. So, at least for a while, you have two certificates for the same domain.

Can a server have two certificates?

The Server Name Indication extension allows TLS to recognize multiple certificates on the same IP address. This means that domains and subdomains, such as example.com and sub.example.com, don't have one over-arching certificate, they can have two certificates -- one for the main domain and one for the subdomain.

Why do we need 2 way SSL?

In Two-Way SSL authentication, the client and server need to authenticate and validate each others identities. The authentication message exchange between client and server is called an SSL handshake, and it includes the following steps: A client requests access to a protected resource.

What happens if I have 2 SSL certificates?

When you install two SSL certificates on the same domain it forces the server to decide which one to serve. In some cases the server will send the most recently installed certificate to visiting browsers assuming it's likely the most secure. In other cases the server may rotate the certificates.

Can you use SSL certificate twice?

The simple answer is a resounding Yes! You absolutely can use one SSL certificate for multiple domains — or one SSL certificate for multiple subdomains in addition to domains.

Can you have two certificate authorities in the same domain?

What is the difference between 1 way SSL and 2 way SSL?

One-way authentication creates a truststore on the client and a keystore on the server. In this example, CA certificate "A" exists in the truststore on the SSL client and also in the keystore on the SSL server. Two-way authentication creates a truststore and a keystore on both the client and the server.

Can a server have 2 domains?

Virtual hosting allows you to host many domains on one server. A server may have extensive resources like HDD space, CPU, RAM, and so on. You can use the same server resources for different sites. It lets you host multiple websites on a single web server instance.
