md5 is not an approved algorithm in FIPS mode, and trying to
instantiate a hashlib.md5() will fail when the system is running in
FIPS mode.
md5 is allowed when in a non-security context. There is a plan to
add a keyword parameter (usedforsecurity) to hashlib.md5() to annotate
whether or not the instance is being used in a security context.
In the case where it is not, the instantiation of md5 will be allowed.
See https://bugs.python.org/issue9216 for more details.
Some downstream python versions already support this parameter. To
support these versions, a new encapsulation of md5() has been added to
oslo_utils. See https://review.opendev.org/#/c/750031/
This patch is to replace the instances of hashlib.md5() with this new
encapsulation, adding an annotation indicating whether the usage is
a security context or not.
In this case, all hashlib.md5() invocations are to run tempest tests
so this is not a security context. With this patch, we can run tempest
tests from a FIPS enabled machine.
