• When the inliner tries to inline something, it should check that the type of the thing being inlined satisfies any type constraints.
• In the proof engine, once inlining has happened, the type checker should be run.
  • This might be related to how I want to use the UniformlyRandom type in game hops to ensure e.g. arguments to a PRF/KDF are uniformly random when applying the hop.

ast.parse(inspect.getsource(f)) chokes on functions that aren't defined at the top level of a module, since the source code for f is indented. (This affects pulling functions from inside classes, for example.) We should be able to change gamehop.inlining.internal.get_function_def to count how much whitespace is as the start of the first line, and then remove that much space from the start of every line.

Eg. multi-party PKE. Reduction guesses a particular key. Fails if adversary selects a different key.

• Calculation of overall advantage when a step has a multiplicative advantage
• Examples of how to step from a game with a random guesses to games without a guess

Will want to re-do PKE from KEM using this. At the end will need to check that output is independent of input bit. Have to figure out how to handle proofs that mix guessing games and distinguishing games.

Maybe using Python's unittest module?

I think the logic for if expressions incorrectly handles the following case:

x = 1
if condition:
    x = 2
    y = 2
else:
    y = 3

Would be cool to be able to output LaTeX source code of a crypto function written in Python. We can recognize the type of statement (assign, function call, if, return), but the user would have to provide mapping of what they want individual variables to be rendered as (e.g., {'kem': '\mathsf{KEM}', 'pk': '\pk', ...}).
