Review Comment:
   it is mainly for slight performance improvement.  `SecureRandom` can 
sometimes block, and also since this is a unit test with dummy data, there is 
no need for strong cryptographic generation of encryption key, so I switched to 
`ThreadLocalRandom`.   I used `ThreadLocalRandom` in this PR for 
`TestS3SecurityUtil` unit test and I remembered this other change from a 
previous PR, so I just changed it as well.
