I won't address any particular encryption algorithms; this is just a pure and simple brute-force attack given precomputed password entropy. Furthermore, quantum computers can use Grover's algorithm for an exponential speed-up; to account for quantum computers using Grover's algorithm, calculate P(n/2, e) instead.

Literal "immunity" is impossible. Lowering this probability to statistical insignificance renders our password practically immune to brute-force attacks.
