Raw Cryptographic Materials
Cryptographic materials classes for use directly with delegated keys.
Warning
Using raw cryptographic materials can be very dangerous because you are likely to be encrypting many items using the same encryption key material. This can have some unexpected and difficult to detect side effects that weaken the security of your encrypted data.
Unless you have specific reasons for using raw cryptographic materials, we highly recommend that you use wrapped cryptographic materials instead.
