Nelder–Mead has often not worked well for me in moderate to high dimensions. I'd recommend trying Powell's method if you want to quickly converge to a local optimum. If you're using scipy's wrappers, it's easy to sw

That code in the EDIT is suboptimal. It doesn't saturate the Kraft inequality. You could make every codeword two bits and still encode 4 symbols, so that would be strictly better.

You're right, GHASH has 128 bits output. I'd wrongly assumed it was 96 from my quick reading of the conclusion on p29: > unless an implementation only uses 96-bit IVs that are generated by the deterministic construction: The t
