Such techologies are actually fairly pointless, as giving both a secret
and a key to that secret to the same party and expecting the secret to
stay that way is completely missing the point of how crypto works. You
can make it difficult for the user to acquire the secret, but there are
just too many attack vectors to keep *everyone* out, and once one person
breaks it, the wonders of the internet mean that pretty much everyone
else can break it as well.
The ease with which even Python bytecode can be monkey-patched at run
time to null out the trusted API calls is likely to make such an
undertaking in Python even more pointless than usual.
Regardless, the answer I gave on python-dev stands: this has nothing to
do with Python as a language or the standard library. The OP is free to
develop whatever Python extension libraries they like and see if they
can attract much outside interest.
