SSL stand for (secure Sockets Layer). It is a standard security technology. In other words, it’s a protocol designed to create an encrypted link/connection between a web server and a browser, which is not easy to hack. With the help of SSL, we can share our private information or sensitive information safely and securely via Internet.
SSL allows confidential information such as social security numbers, credit card numbers, or login credentials to be transmitted securely. Without SSL, data sent between clients and servers is sent in plain text–which makes it really easy to be intercepted. Anyone able to hijack the data stream will have unlimited access to the plain text. With SSL in place, data is encrypted – even if intercepted, it will not be able to be deciphered.
SSL Certificate
SSL certificate is small data file that contains data like organization name, country name, primary domain, sub-domains, expiration data, CA etc, which is provided by the owner of a website at the time of loading SSL certificates. In return, a single IP address is issued to that website, which in turn serves main domain as well as linked sub-domains.
Various Comodo SSL Certificates: There are various SSL Certificates that Comodo supports. These are categorized in three groups:
Single domain
Multiple domain
Wildcard
You can choose from these categories as to which SSL certificates would be more useful in your case as well as would be more cost effective.
Need for SSL Connection-
In normal cases, data is transferred or shared in simple text form, which gives advantage to hackers to misuse or modify it easily, which is a big security threat. To overcome this, SSL provides an encrypted link, which converts the data into non-readable form, and then this encrypted data is transferred between the server and the browser through secure link that nullifies the risk of data being hacked. To get this kind of security, all you need is SSL Certificate.
Comodo provides its services all over the world and had made it easier for its customer to purchase required Comodo SSL certificate online. All you have to do is simply open the site and follow few simple steps/instructions.
Steps are:
Choice of SSL certificate as per the requirement.
To make a purchase, click on button at the top of the page.
Enter details like your region, certificate type, domain name etc.
Now choose tenure of validation of certificate.
Now create a CSR (Certificate Signing Request). Once CSR is complete, an encrypted block of text is provided by the server.
Copy and paste the encrypted block in the application page
Provide the account information
Fill the payment details.
After completing above mentioned steps, you can install required SSL Certificate. Within few minutes, requested SSL certificate will be installed and ready to use.
How SSL Certificate Provides Security-
To establish secure/encrypted connection, these keys work together. This certificate also contains identity of the owner and in technical language it is known as SUBJECT. CSR (Certificate Signing Request) must be created to get a SSL certificate, which in return creates a set of keys (public and private key). Then CSR data file that contains public key is sent to CA (Certificate Authority).
This data file is used for creating data structure to match private key but due to security reasons CA can never see the private key. Once the certificate is issued by CA, install it on your server. When installation of SSL certificate is complete, this server certificate is connected with CAs certificate in order to establish reliability and credibility of SSL certificate.
