What Is Digicert SSL Certificate – Before We Get Into The Topic , Let’s Learn Some Basic Of This Topic

What Is An SSL Certificate?

Creating a trusted atmosphere in which potential clients feel comfortable making transactions is one of the most critical aspects of an internet company. By providing a secure connection, SSL certificates provide a foundation of confidence. Browsers include specific visual cues called EV indicators, which can range from a green padlock to a branded URL bar, to inform visitors that their connection is secure.
SSL certificates have a public and private key pair. These keys are used in conjunction to create an encrypted connection. The “subject,” which is the identity of the certificate/website owner, is also included in the certificate.

You must first create a Certificate Signing Request (CSR) on your server to obtain a certificate. On your server, this operation generates a private key and a public key. The public key is contained in the CSR data file that you give to the SSL Certificate issuer (also known as a Certificate Authority or CA). The CA creates a data structure to match your private key using the CSR data file without compromising the key itself. The private key is never seen by the CA.

WHAT IS AN SSL CERTIFICATE AND HOW DOES IT WORK?

You must install the SSL certificate on your server once you have received it. You also need to install an intermediate certificate, which ties your SSL certificate to your CA’s root certificate and verifies its legitimacy. Depending on your server, the instructions for installing and checking your certificate will be different.
You can see what’s known as the certificate chain in the figure below. It uses an intermediate certificate to connect your server certificate to the CA’s root certificate (in this case, DigiCert).
The fact that an SSL certificate is digitally signed by a reputable CA like DigiCert is the most crucial feature. Although anybody can create a certificate, browsers only trust certificates issued by organizations on their trusted CA list. The Trusted Root CA store is a collection of trusted CAs that comes pre-installed in browsers. An organization must comply with and be audited against security and authentication requirements specified by browsers to be included in the Trusted Root CA repository and so become a Certificate Authority.
An SSL certificate issued by a CA to an organization and its domain/website certifies that the identity of that organization has been verified by a trustworthy third party. Because the browser trusts the CA, it also trusts the identification of that company. The browser informs the user that the website is secure, allowing them to visit the site and even enter confidential information with confidence.

WHAT IS A SECURE SOCKETS LAYER (SSL)?

SSL is a common security protocol for establishing an encrypted link between a server and a client—typically, a web server and a browser, or a mail server and a mail client (e.g., Outlook). TLS, or Transport Layer Security, the successor technology of SSL, is less well-known.
SSL enables the safe transmission of sensitive data such as credit card details, social security numbers, and login credentials. Data exchanged between browsers and web servers are usually transferred in plain text, leaving you open to eavesdropping. An attacker can see and utilize information if they can intercept all data transmitted between a browser and a web server.

SSL is a security protocol in particular. Algorithm protocols specify how algorithms should be applied. The SSL protocol, in this scenario, determines the encryption variables for both the link and the data being transmitted.
The SSL protocol can be used by all browsers to communicate with secure web servers. However, to establish a secure connection, both the browser and the server require an SSL Certificate.

Every day, SSL protects the data of millions of individuals on the Internet, notably during online transactions or when sending confidential information. The lock icon that comes with an SSL-secured website, or the green address bar that comes with an Extended Validation SSL-secured website, has become synonymous with online security. SSL-protected webpages begin with “HTTPS” instead of “HTTP.”

HOW DOES THE SSL CERTIFICATE CREATE A SECURE CONNECTION?

When a browser tries to access an SSL-protected website, the browser and the webserver create an SSL connection through a procedure known as an “SSL Handshake” (see diagram below). It’s worth noting that the SSL Handshake is completely transparent to the user and occurs in real-time.
To establish an SSL connection, three keys are used: the public, private, and session keys. Anything encrypted with the public key can only be decrypted with the private key, and the reverse is also true.
Because encrypting and decrypting using a private and public key requires a lot of computing power, they are only used to produce a symmetric session key during the SSL Handshake. The session key is used to encrypt any transferred data after the secure connection is established.
The browser establishes a secure connection with a web server (website) (HTTPS). The browser asks the server to identify itself.
The server delivers a copy of its SSL certificate, which includes the public key of the server.
The browser checks the certificate root against a list of trustworthy CAs to ensure that the certificate is legitimate for the website it is connected to, that it is not expired or revoked, and that its common name is correct. If the browser trusts the certificate, it uses the server’s public key to construct, encrypt, and send back a symmetric session key.
To begin the encrypted session, the server decrypts the symmetric session key with its private key and sends back an acknowledgment encrypted with the session key.
The session key is now used by both the server and the browser to encrypt any sent data.

Is my certificate SSL or TLS?

To encrypt and safeguard transferred data, the SSL protocol has always been utilized. Only the version number was changed to reflect the change each time a new and more secure version was launched (e.g., SSLv2.0). When it came time to upgrade from SSLv3.0, however, the new version was dubbed TLSv1.0 instead of SSLv4.0. TLSv1.3 is the version we’re using right now.
DigiCert refers to certificates and describes how transmitted data is secured using TLS/SSL because SSL is the more well-known and widely used phrase. When you buy an SSL Certificate from us (for example, Standard SSL, Extended Validation SSL, and so on), you’re actually buying a TLS Certificate (RSA or ECC).
