Q

Data is first encrypted on the client-side before uploaded to Amazon S3. You manage the encryption process, the encryption keys, and related tools

A

Client-Side encryption (CSE)

34
Q

Amazon S3 encrypts your object before saving it on disks in its data centers and then decrypts it when you download the objects

A

Server-Side encryption (SSE)

35
Q

You manage the encryption keys and S3 manages the encryption and decryption process

Q

S3 uses AES-256 encryption keys to encrypt your objects, and each object is encrypted with a unique key

A

SSE-S3 (AES256)

37
Q

S3 uses AES-256 encryption keys to encrypt your objects but the key is managed in a different service, which is AWS KMS
