Server-Side Encryption with S3 Managed Keys, SSE-S3. The encryption process is as follows. Firstly, a client uploads Object Data to S3. S3 then takes this Object Data and encrypts it with an S3 Plaintext Data Key. This creates an encrypted version of the Object Data, which is then saved and stored on S3. Next, the S3 Plaintext Data Key is encrypted with an S3 Master Key. Which creates an encrypted S3 Data Key. This encrypted Data Key is then also stored on S3 and the Plaintext Data Key is removed from memory. The decryption process is as follows. A request is made by the client to S3 to retrieve the Object Data. S3 takes the associated encrypted S3 Data Key off the Object Data and decrypts it with the S3 Master Key. The S3 Plaintext Data Key is then used to decrypt the object data. This object data is then sent back to the client.
