Explanation:
https://docs.aws.amazon.com/AmazonS3/latest/dev/UsingServerSideEncryption.html Server-side encryption is
about protecting data at rest. Server-side encryption with Amazon S3-managed encryption keys (SSE-S3)
employs strong multi-factor encryption.
Amazon S3 encrypts each object with a unique key. As an additional safeguard, it encrypts the key itself with amaster key that it regularly rotates. Amazon S3 server-side encryption uses one of the strongest block ciphers
available, 256-bit Advanced Encryption Standard (AES-256), to encrypt your data.
C:Amazon has recently added a feature that helps encrypt the object on the server side. Amazon S3 Server Side Encryption (SSE) provides you with the ability to encrypt data stored at rest in Amazon S3. With Amazon S3 SSE, you can encrypt data on upload simply by adding an additional request header when writing the object to Amazon S3. Decryption happens automatically when data is retrieved.
