What is the use of encryption and decryption?

• 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.
• 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.
