I have Kafka service which needs 2-way authentication . I have created a truststore in Machine/Broker 1 and M2 , M3 and M4 are keystore . I was told to create a keystore in M2 and copy to other two machines(m3,m4) . Am I compromising the security because If I give the same certificate to M5 , technically it will work right . Where I went wrong in understanding that .
