Disclaimer: Estimates assume an offline attack model. The supercomputer number is an exascale-class, multi-GPU upper bound; the quantum number is a hypothetical future fault-tolerant Grover-style estimate. Real crack time depends heavily on the hash algorithm, salt, KDF cost, rate limits, MFA, and whether the password appears in known leaks or not.
