             Summary: Modernize secret manager default algorithm and key length
                 Key: HADOOP-19869
                 URL: https://issues.apache.org/jira/browse/HADOOP-19869
             Project: Hadoop Common
          Issue Type: Improvement
          Components: security
    Affects Versions: 3.4.3, 3.5.0
            Reporter: Steve Loughran
            Assignee: Steve Loughran


While doing other cleanup, I've noticed that the default checksum algorithm and 
key length for generating secrets (block tokens, job tokens) are out of date by 
modern standards. Not broken, just weak.

Change the defaults
