Amazon S3(Simple Storage Service) object encryption is an invisible shield, silently protecting your data from unauthorized access—whether at rest or in transit.
S3 offers two primary types of encryption: Server-Side Encryption (SSE) and Client-Side Encryption (CSE).
Enabling encryption in AWS S3 is straightforward, allowing you to choose between server-side encryption with AWS Managed Keys or SSE-KMS, and client-side encryption.
With SSE, AWS handles encryption, key management, and decryption on your behalf, while CSE gives you complete control over encryption and key management.
