public sealed class CryptoKey : IMessage<CryptoKey>, IEquatable<CryptoKey>, IDeepCloneable<CryptoKey>, IBufferMessage, IMessage
This is a data encryption key (DEK) (as opposed to
a key encryption key (KEK) stored by KMS).
When using KMS to wrap/unwrap DEKs, be sure to set an appropriate
IAM policy on the KMS CryptoKey (KEK) to ensure an attacker cannot
unwrap the data crypto key.
