Can PEM files be used for Kafka security?

Question

The documentation at http://kafka.apache.org/documentation/#security describes the process of enabling security in Kafka.

It describes the certificates to be in JKS format. Is it possible to use PEM formatted certificates with Kafka?

Just import PEM certificates into .jks store using `keytool`? — Alex Ott, Jan 14 '18 at 10:40

You'll be able to use PEM in Kafka after 2.7.0 is released. Details here. Currently you can also use PKCS12.

No you cannot directly use PEM certificates with Kafka.

This is not a Kafka restriction, it's just that all of the "mainstream" JVMs (HotSpot, OpenJDK, J9) use JKS.

See Import .key and .pem file to jks file and use in Java/Spring for the required steps to import a PEM file into a JKS store.
