It is an old encryption technique that is very well known. For symmetric encryption methods, the sender must share the private key with the receiver to access the data or information. There are two encryption keys based on which different types of encryption work:ġ) Symmetric: It works on a single private key, therefore it is faster than asymmetric encryption (explained in detail in the next bullet). When it reaches us, we’ll decrypt the message using the same key and it will appear to us as: The ciphertext will look like this to a third party: nIssP3KwTm6t7nO27b6MisafLAKQnMC+UDzq/THM6Fv+QWmWpHkZkSEn2d1cBT9WT289y6HyZFpjuJFKTBeJEkJi圓/Fcj8AHGrzOyvJtTdpWHUe3GlzxFVed4UX/yXZdei1xagl+wg+HY5kD9kljDCe+XMVNjXNybcvJXnIiN+EtltIO5ftgbyGVI+A8x+Vms3FzUYFGRZWiDN4SsynTBNaXh+MJOJCaPxgej1nt+QJ1pjzFCxmuWnlRQRonAuiMxgbGKzuEhuOTwRg06dVfj0ZHV19HVyPE94u5UAC4IUAHnSYgJu8r2zLPeER0xlQtC0EeviBlFb9jW1LUglyO1wxH6vWuQu5URCgSY1u7rI= Now, this message will be encrypted using a key. Can you suggest which one will be the best for my website? Kind regards, Emma George.” I want to have the best encryption method to protect my clients’ data. Most of the payments are received through my website. “ Hello GoodCore, I run an online business. Decrypted text (same as the initial plain text).įor instance, you have sent us a message, which goes like this:.So, there are three encryption levels that are at work: But in the digital world, all this is done electronically! She has the same key as yours through which she is able to unlock it and get access to those important documents. Imagine you have put a lock on the box containing important documents with the help of a key. You need to have a randomly generated key before sending the message or data to the person at the receiving end, through which they can decrypt it. In simpler words, encryption uses algorithms to jumble up whatever data you want to encrypt. Now that we are clear on the concept of encryption, let’s have a look at how exactly it works. You can encrypt your data while you are working at it or you are about to send it. It can be done at any given point of the entire data flow it is not an isolated process. This entire process of encoding/decoding is only possible with the help of a digital “key”, which I will explain in detail in the next section.Įncryption is considered as a secure way of transferring or sharing data to avoid third-party intervention. When it reaches to the person at the receiving end, the unreadable data is decoded and becomes readable to the specified recipient only. In technical terms, your shared data is encoded it is converted into an unreadable format. These processes are known as encryption in the modern digital world. In order to avoid such a compromise, one can install certain software/hardware that will ensure a secure transfer of your shared data or information. Since your data traverses over the public Internet, there is a fair chance of data being compromised. When you share any information or data over the internet to another person, it goes through a series of network devices situated worldwide, all of which form part of the “public” Internet network. To begin with, let us understand the concept behind encryption. If you are curious to know, keep reading till the end! Now, you must be wondering what is encryption? How does it work? How many types of encryption are there? Is there any encryption standard that one can follow? What else do you require to protect your data? I will answer all of these questions for you in this article. This is exactly where the benefit of data encryption comes in. Strange? You must be wondering “how did that even happen?” Well, the online page where you entered your bank details was not secured or your data got “stolen” while being transmitted as it was not encrypted. Now, you don’t remember transferring that second $3000 to anyone! The next day you receive another message that $3000 has been transferred to an unknown account. After a few hours, you get a confirmation message from your friend that he has received the money. You enter your bank account details and transfer him the required money. Imagine you and your friend are working in different cities and you have to transfer him $2000 online. Let’s start this article on types of encryption with a little scenario: As a software development company, we realise the importance of cybersecurity, and one of the best ways to ensure maximum security is via encryption.
