What is the purpose of Encryption?

The primary purpose of encryption is to make data unreadable to unauthorized users, especially during transmission or when accessed without proper permissions. This is crucial in protecting sensitive information, ensuring that even if data is intercepted during transfer or accessed illegally, it remains secure and unintelligible to anyone who does not possess the appropriate decryption keys.

Encryption transforms readable data into an encoded format using algorithms and keys, which can only be reverted to its original state with the correct decryption process. This plays a significant role in maintaining data confidentiality, integrity, and security across various applications—from online banking and healthcare records to personal communications.

While creating backups, enhancing transfer speeds, and organizing data are important aspects of data management, they do not directly relate to the primary function of encryption in safeguarding data from unauthorized access.
