Package com.amazonaws.athena.connector.lambda.security

Class NoOpBlockCrypto

java.lang.Object

com.amazonaws.athena.connector.lambda.security.NoOpBlockCrypto

All Implemented Interfaces:

BlockCrypto

public class NoOpBlockCrypto
extends Object
implements BlockCrypto

Implementation of BlockCrypto does a No-OP (nothing) for encrypting and decrypting blocks. This is helpful when you want to disable encryption or do testing without having to handle disabled encryption as a special case in code.
