Class DecryptDeserializer

java.lang.Object

io.macronova.kafka.common.serialization.DecryptDeserializer

All Implemented Interfaces:

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

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

Decrypt data with secret key or certificate loaded from keystore. If chosen cipher requires initialization vector, deserializer expects to read it from the beginning of encoded content. 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 (private key decryption):

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

Deserializer expects input data representation analogical to output generated by EncryptSerializer.
