My idea was that you are assuming that Inside of these presumptions using code to deencrypt the key should be "safe"

Simple example a loop doing XORs with values from a nested table.

XORs are easily reversed.

Plus some rotations if you want and gotos depending on temporary values in the middle.

Sorry, no ready to use suggestions.

Of course one could use B::Deparse to disassemble the Op-tree, but that's always the case.

HTH! :)

update

You could create such an algorithm with random values.

It's only important that

For clarification the algorithm would act here as the key.
