What is Included in a SSL Certificate?

by Peter

What exactly is included in an SSL certificate? An SSL certificate is a digital signature that authenticates a site’s identity and allows an encrypted connection to be established. SSL stands for Secure Socket Layer, SSL Certificates creates an encrypted channel between a browser and a server. SSL certificates can be required when viewing various online media, like websites or email. But SSL certificates are also frequently used for various other purposes, such as authenticating automated systems, creating authentication codes in emails, and displaying the validity of a domain name.

Types of SSL Certificates

There are two different types of SSL certificates. The first one is CA-controlled, which means the certificate authority grants you access to a private key. The second one is self-signed, which means you generate your private key. Self-signed SSL certificates do not provide any encryption. However, they are more trustworthy than controlled SSL certificates because of the absence of a third party.

Uses for SSL Certificates

There are many uses for SSL certificates, from verifying the identity of a website visitor to preventing credit card transactions from being fraudulent. In most cases, an SSL certificate lets users know that the web server they are using is safe and secure. For instance, a site that allows people to make a secure payment through PayPal can indicate that they use PayPal’s Payment Protocol (PTP) when sending payment through their web server.

An SSL Certificate, also known as an SSL Server Hello Word, can be composed of one or more HTTP keys. Each HTTP key has a generated key and is encoded within an optimized format. An HTTP key is only valid for a finite amount of time before it expires. During this time, the webserver maintains records of all the keys that have been stored within it and the digital signature that is included in the generated string. When a user requests a webpage, the web server sends a request to the SSL Certificate provider to request the latest public key.

Trust between Servers and Websites

SSL certificates help establish trust between servers and websites. Once you have established an SSL Certificate, you can be confident that any page viewed on your website will be safe from tampering and should not contain sensitive information. Some of the things that can be contained in an SSL Certificate include the domain name, the name of the organization that issued the certificate, the expiration date, the website’s IP address, and any other relevant information. These details are also commonly referred to as authenticity codes, digital signatures.

Levels of Working

SSL certificates work on two levels, first by authenticating the identities of the servers that send you traffic and second by encrypting all outgoing traffic. Encrypted connections are used in between different Internet networks so that the information sent by you to a friend on Facebook can be encrypted and delivered to their computer safely without anyone in the middle discovering the fact that you’ve encrypted your connection. For example, when you visit an online bank, you generate a user name and then enter the secure connection created between your bank and your account provider. Your bank’s private key is then used to encrypt all transactions you make to the website, and this transaction is only visible to the parties involved in the secure online bank.

Three Different Types of SSL Certificates

There are three different types of SSL certificates: validation, enterprise, and private keys. The validation certificates verify that the IP addresses provided by the client computers match the IP addresses registered with the server. The private key certificate allows for the encryption of SSL keys which are required for authentication purposes. Validation certificates are also combined with the enterprise SSL certificates to ensure that the private key certificate’s IP and name match the ones registered with the website. Lastly, the CA (Certificate Authority) certificate provides the highest level of protection, which verifies that the certificate issued by the CA is indeed the highest level of protection possible.

Conclusion;

SSL certificates help people differentiate between different websites with the same domain but different hosting servers. Apart from that, SSL certificates are used for encryption to help you transmit sensitive data in clear text format over the Internet and help you identify and read all messages you receive in your email. In a nutshell, SSL certificates are vital as they help you secure your communication over the Internet, be it from internal or external parties.
