Python: TrustedPickle.
“TrustedPickle is a Python module that can save most any arbitrary
Python object in a signed pickle file. There are two big differences
between this module and the standard pickle module. First, TrustedPickle
can pickle a module, but the standard pickle module cannot. Second,
TrustedPickle includes a signature that can verify the data’s origin
before the data is unpickled.”
