I pretty much agree with all that has been said.  We should fix it.
SHA-2 makes the most sense today.  And fixing it as a general hardening
measure, rather than an OSSA makes sense.

To the point of wanting to just get all bad crypto algorithms out of
these code bases... the OSSG is working on some gate tools that would
catch such things.  Once those are put in place, it should be much
easier to prevent this kind of thing from happening in the future :-)

  uses a weak hashing algorithm, MD5. It would be pretty simple
  hardening upgrade to use at least hashlib.SHA256.
