What is Encryption

Encryption has become an essential part of our online lives and I probably use it every day without knowing much about it.

At the most basic level, encryption protects the text and data you send and receive online so that they are protected. The idea is that no one can read your usernames, passwords, credit card details or anything else that is important to you. More technically, encryption uses a complex algorithm called encryption to convert plain text into a series of seemingly random characters, or encrypted text that is unreadable to those without a special key.

Your data is transferred as encrypted text and when it arrives at its destination a key is used to turn it back into readable text.

There are many places where you will see encryption online, but two of the most common will be with your Wi-Fi connection and when you are browsing online. Here is a little more about both:

WI-FI

Currently, the strongest security available on a Wi-Fi router is WPA2. WAP means Wi-Fi Protected Access, 2 is the second version of this protocol. It uses 256 bit AES encryption. The 256 bits are exactly a string of 256 1s and 0s that comprise of the key to unlock your data. It would take a very fast computer one billion years to decrypt 128-bit encryption, so version 256 is considered more secure. By the way, AES stands for Advanced Encryption Standard, which is the algorithm that determines how to encrypt your data.

ONLINE BROWSING

When you load a web page, the start of the address bar can begin with “https:” The “s” means secure and means that all communications between your browser and the website are encrypted. Then, when you log in to a website, you can be sure that your data is safe. Websites now also usually put a lock icon in the address bar to give you a visual signal that everything is safe.

As long as you have a Wi-Fi connection that requires a password to log in to the network and are careful about using websites protected by https, your data will be secure.

However, hackers will always focus on the weakest point of digital security, and that remains their password. That is why it is important to always choose a strong password that is very difficult to crack by a computer.

Encryption in Blockchain

So, if we talk about encryption in blockchain, blockchain security methods include the use of public-key cryptography.

A public key is an encrypted long and random-looking string of numbers which is an address on the blockchain and value tokens sent across the network are recorded as belonging to that address.

In Blockchain, encryption is really an important factor for data security. As you know, Blockchain is not centralized. It is a distributed ledger, so obviously people do not want other people to see their personal data.

Here the concept of encryption came, everything thing in blockchain technology is encrypted that is why data stored on the blockchain is generally considered incorruptible.
