SSL Certificates – A Powerful Instrument for Virtual Authentication


While many of us would have regularly heard the term “SSL Certificate”, very few people know what it is or even how it works and since not many of us know what an SSL Certificate is, they might not be conscious of its importance or criticality in the world of computers and web. What you need to consider about SSL.

Specifically termed as Secure Outlet Layer Protocol Certificate, SSL certificate was developed by Netscape to add security factor towards the transactions between browsers as well as web servers. The process employs a third party, a Certification Authority to identify transactions on both ends or in case its difficult to understand that method, in layman’s language SSL Certificate for a website is similar to a Passport or a License that is issued by a reliable source known as Certificate Expert.

To canvas the basic knowledge of an SSL Certificate via a real-world example, let’s think about someone sending an email through a regular postal program in an envelope. Since it is without a security factor, anyone with usage of that envelope can easily access its contents and if the idea looks valuable they might take possession of it or maybe make changes to it.

To remove the long story limit, An SSL Certificate is usually something that encrypts virtual deals or transitions or any change of data over the internet thus rendering it completely secure.

Workflow involving SSL Certificate:

This is how some sort of Secure Socket Layer Method Certificate works.

  • A safeguarded page is requested by way of a browser – HTTP:// normally
  • A public key is dispatched by a web server as well as its certificate
  • The visitor then verifies that the document is issued by a dependable source that the certificate is usually valid and is allied to the website contact
  • Upon proof, the public key is then utilized by a browser essentially for you to encrypt a random symmetric encryption key and is sent to the server with the WEB LINK that is encrypted and essential along with the other encrypted HTTP data.
  • The symmetric truth is then decrypted by a website server using its private essential and the server then employs the symmetric key to decrypt the HTTP data along with the URL.
  • The requested CSS document and HTTP files are then transmitted by the website server encrypted with the symmetric key.
  • And finally, the HTTP data and HTML contract is decrypted by the visitor using the symmetric key plus the information is displayed.

For somebody with very low technical expertise, the above workflow might seem a little complicated. However to get a simple fact that understanding of this, several techie concepts need to be understood which include the Private Key / General public Key, The Certificate, The actual Symmetric Key, Encryption Formula, The hash, Signing, Passphrase, Public Key Infrastructure, and so on

Types of SSL Certificates:

Classes have many types of SSL Certificates, but not every one of them is the same when compared with each other. When it comes to SSL safety on any website, it is essential to consider what type of certificate you receive. Since it’s security software, it essentially serves 2 main purposes.

Wildcard SSL Records: These types of Certificates are mainly useful for websites having sub-websites ensuring the complete protection of all subdomains. Wildcard SSL protection authorizes the protection of numerous aspects of a Web portal together with one SSL Certificate.

In terms of SSL security, one most crucial things to keep in mind while producing a comparison between different types of SSL Certificates is the level of safety offered. However, 128 little encryption is what Industry common is. Even 256 little comparison is available for an elevated fee and some companies also offer 58-bit security to make it less expensive. Common sense is that the higher the security number, the better you get safety.


Since most web-based now becoming virtual and so are giving a thrust to net transactions, with an increased number of internet financial activities, it becomes come across cyber crimes all the more looking out at today’s world climate where cybercrime relation is booming high, having an SSL Certificate protection isn’t more an option but has developed into a bare necessity. Having said it can be highly recommended to adopt SSL encryption with the utmost higher level of security to ensure the complete safeguard of sensitive data in addition to various aspects of a website.
