Encrypting and decrypting messages with Spring Kafka

问题

I am using Spring Kafka and one of the topics contains messages with personal data. Is there any way I can configure Spring Kafka to automatically encrypt messages in a Producer/decrypt messages in a consumer or would I have to do it manually?

回答1:

There is nothing built into Spring or Kafka (although you can use SSL on the wire to prevent snooping.

For application-level encryption/decryption, you would need to implement it.

You can separate the concern from your business logic by using a ProducerInterceptor and ConsumerInterceptor (Kafka) or RecordInterceptor (Spring).
