public enum CryptoMode extends Enum<CryptoMode>
Enum Constant and Description |
---|
AuthenticatedEncryption
Authenticated encryption mode using AES/GCM, AESWrap, etc.
|
EncryptionOnly
Deprecated.
This feature is in maintenance mode, no new updates will be released.
Please see https://docs.aws.amazon.com/general/latest/gr/aws_sdk_cryptography.html for more information.
|
StrictAuthenticatedEncryption
Strictly enforce the use of authenticated encryption via AES/GCM,
AESWrap, etc., and will throw security exception if an S3 object
retrieved is found to be not protected using authenticated encryption.

public static final CryptoMode AuthenticatedEncryption
When decrypting with AES-GCM, read the entire object to the end before you start using the decrypted data. This is to verify that the object has not been modified since it was encrypted.
public static final CryptoMode StrictAuthenticatedEncryption
Please note the limitation on the maximum message size in bytes that can be encrypted under this mode is 2^36-32, or ~64G, due to the security limitation of AES/GCM as recommended by NIST.
