Encrypting or Decrypting a Large Amount of Data Key rotation mechanism Keys that are widely or repeatedly used are insecure. DEW allows you to periodically rotate keys and change the key materials to comply with encryption best practices.
Symmetric keys are suitable for encrypting and decrypting data. Asymmetric key ECC EC_P256 EC_P384 Elliptic curve recommended by NIST Digital signature and signature verification Asymmetric key ML-DSA NOTE: To enable the ML-DSA algorithm, submit a service ticket.
Feature Description Phase Document 1 Key import A CMK contains key metadata (key ID, key alias, description, key status, and creation date) and key materials used for encrypting and decrypting data.

Encrypting Data with a DEK KMS does not support data encryption with DEKs. You can use other encryption libraries (for example, OpenSSL) to encrypt data with DEKs. Obtain a plaintext DEK by referring to Creating a DEK. Use the plaintext DEK to encrypt data.
Envelope Encryption Envelope encryption is the practice of encrypting data with a DEK and then encrypting the DEK with a root key that you can fully manage. In this case, CMKs are not required for encryption or decryption. DEK A data encryption key (DEK) is used to encrypt data.
