HOSTING / SECURITY
One of the most important components of online business is creating a trusted environment where potential customers feel confident in making purchases. SSL certificates create a foundation of trust by establishing a secure connection and browsers give visual cues, such as a lock icon or a green bar, to help visitors know when their connection is secure.
Secure Sockets Layer certificates have a key pair: a public and a private key. These keys work together to establish an encrypted connection. The certificate also contains what is called the “subject,” which is the identity of the certificate / website-owner. To get a certificate, you must create a Certificate Signing Request (CSR) on your server. This process creates a private key and public key on your server. The CSR data file that you send to the SSL Certificate issuer (called a Certificate Authority or CA) contains the public key. The CA uses the CSR data file to create a data structure to match your private key without compromising the key itself. The CA never sees the private key.
Once you receive the SSL certificate, you install it on your server. You also install an intermediate certificate that establishes the credibility of your SSL Certificate by tying it to your CA’s root certificate. The instructions for installing and testing your certificate will be different depending on your server. Below, you can see what is called the certificate chain. It connects your server certificate to your CA’s (in this case DigiCert’s) root certificate through an intermediate certificate.
Trusted Secure Sockets Layer
The most important part of an SSL certificate is that it is digitally signed by a trusted CA, like DigiCert. Anyone can create a certificate, but browsers only trust certificates that come from an organization on their list of trusted CAs. Browsers come with a pre-installed list of trusted CAs, known as the Trusted Root CA store. In order to be added to the Trusted Root CA store and thus become a Certificate Authority, a company must comply with and be audited against security and authentication standards established by the browsers.
An SSL Certificate issued by a CA to an organization and its domain / website verifies that a trusted third party has authenticated that organization’s identity. Since the browser trusts the CA, the browser now trusts that organization’s identity too. The browser lets the user know that the website is secure, and the user can feel safe browsing the site and even entering their confidential information.
