In this post I am going to tell you something about what is SSL (Secure Socket Layer) and what are the key benefits of having SSL certificates in your website, so in case you are interested in web development then this is for you!
Before starting with SSL certificates let me tell you some of the attacks a hacker or an intruder can perform on a network.
#1 Interruption – In this source is not allowed to send information to the user. This can be done by sending junk packets in order to block the traffic.
#2 Interception – This is the attack on confidentiality. A hacker can get all the information which is being sent to the destination.
#3 Modification – In this not only the intruder will get the information but it will make some changes and then send it to the destination.
#4 Fabrication – This attack is on authenticity, in this the attacker sends the information to the destination and it will occur to the destination that the information is coming from an authenticated sender.
What is SSL (Secure Socket Layer) ?
SSL is a protocol , it was first used by Netscape to ensure security of data through HTTP, LDAP , POP3 in order to hide or protect sensitive information that are flowing through public communication network . It runs on top of TCP to provide secure transmission of data.
SSL Certificates provides security by encrypting the data transmission between the user (browser) and the server. Websites having SSL certificates have a padlock in the URL. Whatever data that you are sending goes in the network, SSL makes sure that this transmission of data takes place in an encrypted form so that even if the intruder spoofs into the network will not be able to read the data. This technique of data encryption is called CRYPTOGRAPHY.
For communication over a network 2 keys are used, one is the public key and other is the private key. The sender will be having its public and private key and the user will have its own public and private key. These keys are used to encrypt and decrypt the data which is being send over the network. To give you an example suppose a sender wants to send some information to a user. In order to encrypt the data which is being send across the network there a basic cryptographic technique is used
Let sender be A and client be B.
A encrypts data using public key of B and sends it to B. Data in an encrypted form is known as cipher text. Then B decrypts the data using its own private key , eventually what B will get will be a original text which was sent.
NOTE : Public keys are shareable while Private keys are not. Private key of a B will only be known to be known to B and nobody else.
Even if anyone spoofs in the network he will still not be able to know the plain text.
With SSL Certificates the client gets authenticated that the information is coming from a trusted server. This is also done by using public key and private key.
I will explain this further with an example, let A be the sender and B the receiver.
It order to authenticate that whatever data B is receiving is coming from A and not by some hacker or intruder. A encrypts the data using its own private key i.e. private key of A; the encrypted data is the cipher text. The cipher text is then received by B , it decrypts it by using A’s public key , if B gets a proper and readable plain text then that ensure that it has come from A and not from some other person because A’s public key was used to decrypt the data.

If your website is such that it requires some online transactions then for your website SSL certificates is a must. Online transactions requires sensitive data like credit card details or account number to flow through network. If your website does not have SSL security then number one no customer is going to trust your website when it will come to giving personal details or sensitive information like credit card number , besides even if someone does perform online transaction chances are that an intruder can spoof into the network and get all the sensitive details . The Importance of SSL Certificates in eCommerce business is to build customer trust & provide online security and prevent cyber threats.
Each and every business can choose SSL Certificates as per their requirements. If you own any eCommerce business and need SSL Certificates then EV certificate is best choice for your website.
Pro Tip: Always choose SSL Certificates which provides 99% browser compatibility & 100% support.
ClickSSL is one of the reputed names in the industry and authorized seller of SSL Certificates which provides Certificates from trusted brands like GeoTrust, Thawte, Semantec and RapidSSL at very reasonable price compare to industry price.
SSL Certificates is not restricted to a particular application; any application running of top of TCP can use SSL to provide secure data transmission. Initially SSL was designed for only 3 applications which were
#1 HTTP: It is used to communicate between web server and web browser.
#2 LDAP (Lightweight directory access protocol): Some information is located in some central place. A request may be send to directory server and it will provide you with the information. Used by email systems.
#3 POP3: a protocol using which email system retrieves mail from the mail server.
SSL has a 2 layer protocol. The lower layer is called SSL record layer protocol which requires data security and integrity.
SSL record layer protocol sits on top of TCP and ensures that data is being transmitted in a secure manner, however before transmission of data a connection needs to be established between the sender and the receiver, for that higher level protocols are used. Once this message goes from client to server and vice versa for acknowledgement. then we have SSL handshake protocol which is used to initiate a session between user and a client.
The last thing is that it is supported by all HTTP servers; besides all popular browsers come with SSL enabled software. Browsers like Mozilla Firefox , Google chrome , Internet Explorer , Safari etc are SSL enabled.
