Thanks for taking part in this discussion. The attack with 1/e memory was
pretty awesome! I never looked at cases where t_cost > 1.
While your algorithm is cool, and showed a weakness in Argon2i, I still
think your algorithm is too slow. How fast can you fill memory?
Memory*time defense goes as the square of this number. Some good
algorithms fill 4MiB in 1ms.
