In the AWS Encryption SDK, data is encrypted using a DEK. This DEK is then encrypted with a Key Encryption Key (KEK), usually managed by AWS Key Management Service (AWS KMS) or another key management infrastructure. The encrypted DEK is stored alongside the encrypted data (ciphertext). This allows the SDK to manage the DEKs seamlessly.

When using the AWS Encryption SDK, it is a common practice to encrypt the data encryption key (DEK) along with the data. The DEK is used to encrypt the actual data, and it is itself encrypted using a key management system, often called a key encryption key (KEK). This encrypted DEK is then stored alongside the encrypted data.
