What is the use of [encryption](https://www.mindstick.com/articles/44101/encryption-101-a-broad-overview) and decryption? ## Answers ### Answer by Hitesh Vohra - **Encryption** is a technique for transforming data into a form that is unrecognisable. This revised version of the message differs significantly from the original. Because senders utilise an encryption technique, a hacker will not be able to read the data. Key algorithms are commonly used to encrypt [**data**](https://answers.mindstick.com/qa/96912/what-is-a-data-cable). - Data is encrypted to protect it from being stolen. Many well-known companies, on the other hand, encrypt data to keep their trade secrets hidden from competitors. - **Decryption** is the process of turning encoded/encrypted data into a form that a human or a machine can read and understand. This method involves manually decrypting the text or utilising the same keys that were used to encrypt the original material. - Protects sensitive information such as passwords and login ids. - Ensures that private information is kept secret. - Assists you in verifying that the document or file has not been tampered with. - The encryption technique also protects IP and prevents plagiarism. - This is useful for network communication (like as the internet), where a hacker can simply obtain unencrypted data. \ **Read More: [Explain Data Encapsulation?](https://answers.mindstick.com/qa/97013/explain-data-encapsulation)** --- Original Source: https://answers.mindstick.com/qa/97011/what-is-the-use-of-encryption-and-decryption Copyright © MindStick Software Pvt.
