1.4. Seamless FIPS support

When running in the FIPS mode, SCRAM-SHA-512 passwords need to be at least 32 characters long. From Streams for Apache Kafka 2.3, the default password length in Streams for Apache Kafka User Operator is set to 32 characters as well. If you have a Kafka cluster with custom configuration that uses a password length that is less than 32 characters, you need to update your configuration. If you have any users with passwords shorter than 32 characters, you need to regenerate a password with the required length. You can do that, for example, by deleting the user secret and waiting for the User Operator to create a new password with the appropriate length.
