What does encryption do to data?

Encryption is a process that transforms data into an unrecognizable format, making it unreadable to unauthorized users. This transformation typically involves the use of algorithms and a key to encode the information, ensuring that only individuals with the correct decryption key can access the original data. This process is essential for protecting sensitive information, such as personal details, financial transactions, and confidential communications, from cyber threats and unauthorized access.

The other options do not accurately describe the role of encryption. For example, wiping data permanently refers to deletion processes, while data compression involves reducing the size of files to save storage space. Organizing data for better retrieval relates to data management, not encryption. Therefore, the essence of encryption lies in its ability to secure data by making it inaccessible without proper authorization.
