#https certificate

If you are technically not very sound and do not understand most of the terms used, then this article is specially written for you. In this article, we will discuss SSL, TSL, SSL certificate, and HTTPS in detail, and in a language which is easy to understand.

SSL: In simple words, SSL is a technology which safeguards information, which is being transferred from one system to another from hackers or any other third party by creating an encrypted link between the two systems. This link has to be secured so that no hacker can misuse or modify the information or data. To achieve this kind of security, data has to be encrypted to make it impossible to read. With the help of this encrypted link, the data transferred between the browser and the server or, in some cases, one server to another remains safe and secured.

SSL Certificate: To get a secure connection or SSL connection between the browser and server, there is a need for SSL certificate. The information SSL Certificate carry is a domain name, company/organization name, and complete address along with the country name. Along with these details, additional information that the certificate contains is the date of expiration, which thoroughly depends upon the tenure you have opt for, and CA (Certification Authority) details. CA is the entity, which is responsible for issuing SSL Certificate

Whenever a browser makes a connection with the server, it checks the SSL certificate of that particular site and its expiration date. Along with this, the authenticity of the Certification Authority (CA) is also verified.

TLS: TLS stands for Transport Layer Security. It is similar to SSL but is more secure. In simple words, it is an updated version of SSL. However, SSL is the most commonly used term, so if you bought latest SSL and want to go for TLS instead, you don’t have to spend a single penny because most probably the latest SSL which you already have is actually a TLS certificate.

SSL certificate is a small data file that contains data like organization name, country name, a primary domain, sub-domains, expiration data, CA etc, which is provided by the owner of a website at the time of loading SSL certificate. In return, a single IP address is issued to that website, which in turn serves main domain as well as linked sub-domains. It means that it will not only provide internet security to the main domain but also, to other sub-domains which are linked with the main domain.

Need for SSL Connection

In normal cases, data is transferred or shared in simple text form, which gives an 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 a non-readable form, and then this encrypted data is transferred between the server and the browser through a secure link that nullifies the risk of data being hacked. To get this kind of security, all you need is the SSL Certificate.

How SSL Certificate Provides Security

SSL certificate has a pair of keys; one is a public key and another one is a private key. To establish a secure/encrypted connection, these keys work together. This certificate also contains the identity of the owner and in technical language, it is known as SUBJECT. CSR (Certificate Signing Request) must be created to get an 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 a data structure to match private key but due to security reasons, CA can never see the private key.
