[jira] [Comment Edited] (FLUME-3406) Inflight events in file channel should not be using MD5 for integrity purposes

    [ https://issues.apache.org/jira/browse/FLUME-3406?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17504489#comment-17504489 ]

OK, then we agree that MD5 is fine because there is no security issue here. We aren't trying to security anything. It is purely a hash to validate what is being read matches what was written.

> FlumeEventQueue's inner class InflightEventWrapper uses MD5 for calculating a digest of inflight events. MD5 has been considered unsuitable for cryptographic usage such as for integrity checks for many years now. This should migrate to SHA-256 at least.
