What is encryption? What is the use of this?

Encryption is a kind of technology. Encryption can protect your data transmitted, received, & stored using the device you choice. Encryption technology can provide high security for everything. All the kind of text messages, Audio messages, Media messages to banking information on your Mobile phone.

There is no limit to the interest and fascination many people have with cryptography. Can you tell me more about encryption? In this post you will Know about this point:
1. Encryption key
2. How encryption works
3. Why encryption is important
4. Disadvantages of encryption

What is encryption?

Encryption is the process by which files are converted into a format that can be accessed with a secret code or decryption key. Provides security for sensitive information.
Your personal information is stored online on various websites and servers. And this data is not stored directly in plain text language, but as a pattern, which is only visible through the decryption key. In other words, encryption is a secure element of various information online or offline. Encryption transforms information into scattered data that cannot be seen with the naked eye. However, with a specific “decryption key”, the encrypted information can be restored as before. The opposite of encryption is “decryption”.

How does encryption work?

Encryption is the process of converting plain text, such as an email or text message, into an unreadable format called “ciphertext.” Encryption is used to protect the privacy of digital data that is stored on your computer or transmitted or stored on the Internet.

As long as the encrypted message reaches the intended person, it’s fine. Both sender and receiver have a secret encryption key that unlocks this message, which works automatically.

Encryption type

Different types of encryption have been created with different requirements and security in mind. Let’s look at some popular encryption examples.

Data Encryption Standards

The Data Encryption Standard, or DES, is a basic level encryption standard. IBM designed it in the 1980s. Advances in technology and declining hardware values ​​have weakened the delivery of sensitive data. 56-bit encryption technology.

Triple DES

Triple DES uses three 56-bit keys by default which provide 3x more protection than the original DES. However, it is currently not used much.


RSA is a cryptographic system based on the first letters of the names of three computer scientists (Rivest-Shamir-Adleman) who use strong and popular cryptography. It is widely used by secure data or exchange.

Advanced Encryption Standard (AES)

The Advanced Encryption Standard (ES) is an encryption method used by the US government, first published in 1997. It is widely used worldwide.

Two fish

Tufish is one of the fastest encryption algorithms, and in many cases slightly faster than others. It’s free, so anyone can use it with free software and hardware.


Most websites provide “Secure Sockets Layer” or SSL protection by encrypting your data. This protects your website from data leaks in transit.

After accessing a website, if there is a lock icon in the URL bar and https://s, it means that the website is using encryption technology. This means that no one else can see information coming to you from this site and information going from you to this site. Even your Internet service provider will not get that information.

Why encryption is important?

Encryption is a very important issue in the internet world. Let’s talk about the importance of encryption.
Internet privacy. Encryption ensures that your personal information is not displayed to anyone other than the person/device who wants it. The highest level of security is achieved using encryption technology.

However, you should check this yourself. The first condition of online privacy is to ensure that your email is sent using an encrypted connection.
Almost all email clients have different encryption settings in their settings. If you check your mail in your web browser, it is your responsibility to ensure that the website has SSL encryption after your visit.

business hacking

Driven by several international organizations, cybercrime is now a global business. The inefficiencies of these encryption technologies often result in large-scale data breaches.
law enforcement. It is the duty of a citizen of a country to use cryptography to comply with the rules and standards of the law. It is also used for customer data security purposes.

The difficulty of encryption

It is designed to protect your data, but you can use encryption if you wish.
Cybercriminals lock your device with encryption and ask for money. It is a phenomenon of ransomware, but it is not new. This ransomware can harm not only individuals but also organizations. Ransomware attacks are often carried out on specific computers.
Attackers try to encrypt different types of devices on your system, including computers, servers, and ransomware.

Insert the wire. Sometimes there is a demand for ransomware before providing the encrypted data encryption key.

So we learned how encryption works. You also learned about different types of encryption. What do you think about encryption? Let us know in the comments section.
