Description

SSE-C (Server-Side Encryption with Customer-Provided Keys) allows users to manage their own encryption keys while AWS S3 handles the encryption and decryption process.

Features

• User-Controlled Keys: Users provide their own encryption keys.
• No Additional Costs: No extra charges for key management.
• Integration: Works seamlessly with Amazon S3 storage service.
• Data Encryption: S3 encrypts data at rest using customer-provided keys.
• Flexibility: Allows users to change encryption keys as needed.

Limitations

• Key Management Responsibility: Users must securely manage and store their keys.
• No Automatic Rotation: Keys are not automatically rotated; users must handle this manually.
• Complexity: Requires additional setup and maintenance for key management.
• Loss of Keys: Data is irretrievable if keys are lost or compromised.

Use Cases

• Highly Sensitive Data Storage: Encrypting highly sensitive data where organizations need full control over encryption keys.
• Custom Encryption Policies: Implementing custom encryption policies that require user-provided keys for compliance or security reasons.
• Secure Data Transfer: Ensuring secure data transfer to and from S3 where the organization manages encryption keys to maintain control and compliance.
