Server-side encryption with AWS KMS keys (SSE-KMS) Answer: B. The data needs to be encrypted before sending it to Amazon S3 so it requires client-side encryption.
If not set then the value of the AWS_SECRET_ACCESS_KEY, AWS_SECRET_KEY, or EC2_SECRET_KEY environment variable is used. If profile is set this parameter is ignored. Passing the aws_secret_key and profile options at the same time has been deprecated and the options will be made mutually exclusive after 2022-06-01.
S3 Encryption Metadata
Key Management in Secret Server Cloud allows you to add an additional layer of encryption using a third-party provider to protect these encryption keys for added protection and control. To do this you must first set up your own encryption key with a third party that you fully control, and then provide Secret Server limited access to it.
1. For data security, you can use server-side encryption with AWS KMS master keys to encrypt data stored in your data stream. AWS KMS allows you to use AWS generated KMS master keys for encryption, or if you prefer you can bring your own master key into AWS KMS.

Amazon encrypts the key with a master key, which rotates regularly. AWS Key Management Service (SSE-KMS) Allows you to audit trail (who and when used the key), extra cost and you manage the master key. Customer provided (SSE-C) User manages the keys but encryption done by Amazon. User encrypts the data on client-side and uploads to S3.

Client-Side Encryption with KMS Managed Keys, CSE-KMS. The encryption process is as follows. Using an AWS SDK, such as the Java client, a request is made to KMS for Data Keys that are generated from a specific CMK. This CMK is defined by providing the CMK-ID in the request. KMS will then generate two Data Keys from the specified CMK.
