What is the primary purpose of encryption?

The primary purpose of encryption is to convert data into a secure format that can only be accessed and understood by authorized parties. This process transforms plaintext into ciphertext using algorithms and keys, making the data unreadable to anyone who does not possess the corresponding decryption key. The importance of encryption lies in its ability to protect sensitive information from unauthorized access and cyber threats, such as data breaches and eavesdropping, ensuring confidentiality and integrity.

Unlike converting data to an easily readable format, encryption specifically aims to obfuscate the data, making it secure rather than accessible. Compression focuses on reducing the file size for faster transmission, which does not involve security. Storing data in a database pertains to data management rather than its secure transmission or access, and while databases may use encryption, the act of storing itself does not define the purpose of encryption. Thus, the focus of encryption is clearly on securing data for only those who are authorized to view it.
