== Testing in FIPS 140-2 mode

We have a CI matrix job that periodically runs all our tests with the JVM configured
to be FIPS 140-2 compliant with the use of the BouncyCastle FIPS approved Security Provider.
FIPS 140-2 imposes certain requirements that affect how our tests should be set up or what
