Data Encryption: Why It Matters and How to Use

Introduction

Have you ever wished you could keep anything private? We can do this in the digital world by using encryption. It seems like a really robust lock on your information. Let’s take a look at encryption, why it matters, and how it can help keep us secure while we’re online.

What is Data Encryption?

Visualize that you are the proud owner of a one-of-a-kind box that is safely locked. You secure the journal inside so no one may see your private thoughts. Data encryption follows the same rules when working with digital data. The thief has jumbled up all of your data, including images and messages. You can’t utilize them for anything until you have the deciphering key.

Here is a straightforward approach to dealing with that:

  • “Please, meet me at the park,” was the message you received.
  • It is encrypted further. The string “Xffk fx bk kif qbsl” is incomplete because it lacks two characters.
  • It is impossible to read the original message without the right key.

Using this method, your data is more secure from unauthorized access.

Why Does Data Encryption Matter?

Nowadays, a lot of people share a lot of stuff on the internet. We use apps to stay in touch with friends and family, pay for things using credit cards, and send emails. The data can fall into the wrong hands if it isn’t encrypted. At this point, encryption becomes useful. Here are some reasons why encryption is crucial:

  • Keep your secrets private: You don’t want everyone to read your diaries. Encryption helps keep your private information private.
  • Protect your money: When you make an online purchase, encryption keeps your credit card information safe. 
  • Protect yourself from criminals: Encryption makes it more difficult for thieves to deceive you or steal your identity.
  • Encourages Candid Discussion: Some establishments have policies in place that penalise people for what they say. Their talks are protected, in part by encryption.
  • Play by the rules: Companies are required by law to keep customer information safe. They are able to do that with encryption.

Types of Encryption

Just as there are several kinds of door locks, there are various methods for encrypting data. Let’s examine a few typical kinds:

  • Symmetric Encryption: It’s similar to owning a single key that can open and lock doors. It is quick and effective for safeguarding data on your own device.
  • Asymmetric Encryption: For locking (encrypting), a public key is used, and for unlocking (decrypting), a private key is used. It functions similarly to a mailbox that anybody may fill up, but you are the only one with the key to access and view the contents.
  • End-to-End Encryption: This is used by messaging applications. Your message is locked when you send it and only becomes unlockable when your buddy receives it. Not even the app developers are able to read it between them.
  • Full Disk Encryption: The information stored on your device is safeguarded by that. It’s like enclosing your whole gadget in a force field.

How Encryption Works: A Simple Explanation

Let’s have a look at an understandable breakdown of how encryption functions:

  • The Plain Text: This is the original data or message you sent. The reason “plain text” is so popular is because it’s simple to read and understand.
  • The Encryption Algorithm: This is like to a set of guidelines for manipulating your message. Computers utilise a certain mathematical formula.
  • The Crucial Point: The program scrambles and decodes the message using this secret code. In most cases, it’s a long string of numbers and letters.
  • The Ciphertext: Once your communication has been encrypted, it looks like this. It seems to be a random collection of characters.
  • Decryption: After removing the ciphertext, this process returns the message to its original form. Both the algorithm and the key are used.

Here’s a simple example:

  • Plain text: “Hello”
  • Crucial Point: 3 (move every letter in the alphabet by three positions)
  • Ciphertext: “Khoor”
  • To Decrypt: Move each letter back three positions

Common Uses of Encryption in Everyday Life

You come with encryption on a regular basis, sometimes without even recognizing it. Here are a few typical instances:

  • Websites with HTTPS: A lock symbol next to the URL of a website indicates encryption is in place on that website. Your information is protected by encryption.
  • Messaging Apps: Numerous well-known applications, like Signal and WhatsApp, use encryption. You may keep your communications secret by using it.
  • Wi-Fi Networks: Data is encrypted when you connect to a Wi-Fi network using a password. It safeguards the information you transmit and receive.
  • Online Banking: To protect your money and financial information, banks utilise strong encryption.
  • Smartphones: A lot of phones encrypt every bit of data they hold in case you misplace or steal the phone.
  • Email: There are email providers that provide encryption. It encrypts your communications as they are sent over the internet.
  • File Storage: Encrypting data is a common practice used by cloud storage providers. When you save the files online, they do this action.

How to Use Encryption in Your Daily Life

Now that you understand the significance of encryption, let’s examine several methods for using it to safeguard your data:

  • Use Strong Passwords: Secure passwords do not indicate encryption. However, they are the first line of defense for your data. Make lengthy passwords that combine symbols, numbers, and characters.
  • Enable Two-Factor Authentication: This increases security even more. It needs an additional form of identity, such as a code sent to your phone.
  • Use HTTPS Websites: When you visit a website, make sure the URL bar says “https://” rather than “http://” and look for the lock symbol.
  • Encrypt Your Devices: Activate the PC, tablet, and phone’s built-in encryption. This option is often located in the security settings of the majority of devices.
  • Use a VPN: Your whole internet data is encrypted when you use a Virtual Private Network (VPN). This is very helpful while using free public WiFi.
  • Choose Encrypted Messaging Apps: For your most private interactions, choose applications that have end-to-end encryption.
  • Encrypt Sensitive Files: Make use of software that encrypts data. Key documents stored on your PC or in the cloud will be safeguarded.
  • Keep Software Updated: Better encryption techniques and security enhancements are often included in regular upgrades.
