> Key: KAFKA-3987
> URL: https://issues.apache.org/jira/browse/KAFKA-3987
> Project: Kafka
> Issue Type: Improvement
> Components: config
> Reporter: Luciano Afranllie
> Priority: Minor
> Fix For: 0.10.1.0
>
>
> In order to be able to do deployments of Kafka that are FIPS 140-2
> (https://en.wikipedia.org/wiki/FIPS_140-2) complaint one of the requirements
> is not to use MD5.
> Kafka is using MD5 to hash message keys in the offset map (SkimpyOffsetMap)
> used by the log cleaner.
> The idea is to be able to configure this hash algorithm to something allowed
> by FIPS using a new configuration property.
> The property could be named "log.cleaner.hash.algorithm" with a default value
> equal to "MD5" and the idea is to use it in the constructor of CleanerConfig.
