Server-Side Encryption with Customer Provided Keys, SSE-C. The encryption process is as follows. Firstly, a client uploads Object Data and the Customer-provided Key to S3 for a HTTPS. It will only work with the HTTPS connection. Otherwise, S3 will reject it. S3 will then use the Customer-provided Key to encrypt the Object Data. S3 will also create a sorted HMAC value of the Customer-provided Key for future validation requests. The encrypted Object Data, along with the HMAC value of the Customer Key is then saved and stored on S3. The Customer-provided Key is then removed from memory. The decryption process is as follows. A request is made by the client via HTTPS connection to S3 to retrieve the Object Data. At the same time, the Customer-provided Key is also sent with the request. S3 uses the HMAC value of the same key to confirm it's validity of the requested object. The Customer-provided Key is then used to decrypt the encrypted Object Data. The Object Data is then sent back to the client.
