Describe the role of encryption

Encryption plays a crucial role in securing data by converting it into a format that is unreadable without the appropriate decryption key. Its primary functions are:

1. Confidentiality: Encryption ensures that sensitive information remains private and protected from unauthorized access, even if intercepted or accessed by unauthorized individuals.

2. Data Protection: It safeguards data both at rest (stored data) and in transit (data being transmitted over networks) from unauthorized viewing or tampering.

3. Compliance: Encryption helps organizations meet legal and regulatory requirements for data protection and privacy.
