Class EncryptSerializer

java.lang.Object

io.macronova.kafka.common.serialization.EncryptSerializer

All Implemented Interfaces:

java.io.Closeable, java.lang.AutoCloseable, org.apache.kafka.common.serialization.Serializer<byte[]>

public class EncryptSerializer
extends java.lang.Object
implements org.apache.kafka.common.serialization.Serializer<byte[]>

Encrypt data with secret key or certificate loaded from keystore. Whenever required, serializer generates random initialization vector and prepends it to the output byte array. Length of initialization vector is dynamically calculated based on chosen cipher suite (see EncryptionHelper.ivLength(String, Cipher)).

Example configuration (secret key):

 transformation = AES/ECB/PKCS5Padding
 secret = 770A8A65DA156D24EE2A093277530142
 

Example configuration (public key encryption):

 transformation = RSA/None/PKCS1Padding
 key.store.path = /tmp/keystore.jks
 key.store.password = changeit
 key.store.alias = key1
 

Output data representation:

 +------------------------------------+
 | initialization vector  | encrypted |
 | (optional, 8-16 bytes) |   data    |
 +------------------------------------+
