What is data encryption?
In today's time when human beings have started spending most of their time on computers and internet, the problem of data theft by hackers has increased a lot. There was a time when thieves used to steal from houses but now most of the thefts, frauds and scams are being done by computers.
Thieves can steal your data and use it in many wrong ways and harm you. Explain that the technique of encryption has been born only to avoid the problem of data theft. Today through this article we will tell you what is data encryption.
What is the meaning of encryption
First of all, let us tell you what the English word data Encryption means. So friends, data encryption is called code writing in simple language. Explain in simple language, encryption means to secure any data file or information through code.
Encryption = Converting to code language
Encryption is the process in which information or any data file is transformed into an unreadable form using an algorithm so that unauthorized users cannot read it. Explain in simple words, protecting any data through code is called encryption. Once any information or data file is encrypted, only the person who has its decryption key or password can read it.
The data file or information before encryption is called Plaintext while the information or data file after encryption is called Ciphertext.
This whole process of data encryption and decryption is called cryptography. Cryptography technology has been brought in so that no third party can steal and read this information while sharing any file or information by any two persons. Explain that there are many types of cryptography and today cryptography technology is also used to protect credit card and debit card numbers.
Types of encryption
There are two main types of encryption. One is Symmetric Encryption and the other is Asymmetric Encryption. Let us explain these in detail.
1. Symmetric Encryption
Symmetric encryption has the same key of encrypting data and decrypting data. Being the same key, in this process of encryption, the user who encrypts the data has to share the encryption key with every user to whom he wants to send this data. This is why this process of encryption is also called Shared Encryption.
2. Asymmetric Encryption
In the process of asymmetric encryption, there are two keys, data is encrypted with one key and data is decrypted with the other key. In this case, while encrypting, the user keeps a key while the decryption key is publicly shared with the people to whom he wants to send data. This process of encryption is also called Public key encryption. The same Encryption key is also used in the SSL (Secure socket layer) which converts Http to Https in the Url of the website.
