I just read that Facebook is going to have 600 000 units of Nvidia H100 class GPUs by the end of year. What does that kind of processing power do for password cracking? Think what if NSA could order FB to run their infrastructure for one hour? How long passwords would need to be to still resist this?

Given that some countries/nations now have access to 150-500+ superfast Nvidia cards, what kind of processing power (cpu/gpu) does the NSA have? Have they placed similar orders at Nvidia?

  They build their own chips and have for some time now. My guess is they’re 10-15 years ahead of what’s publicly available.

    Their chips aren't any better, in fact they're probably quite a few generations behind what's available commercially due to various certification requirements etc. HOWEVER, last I checked, their budget for this sort of thing was 11 billion dollars a year, and that's where their advantage lies. Their chips are designed to be maximally power performant for the tasks they're doing, and they have a fuckton of them.

If everyone starts using Argon2 with good parameters, not much!

Insiders say that NSA had quantum computers for decades. And there is also Space Force. They can crack EVERYTHING. Of course I cannot prove this, but I trust my sources. Will not tell here.

  We have no reason to believe you. However, there is one party who really benefits from people considering all encryption weak and all cryptography broken: the NSA.

    I didn't pretend to be believed. It's not that cryptography is "weak" or "broken", but people should be aware that (except from God Himself), there is also a purely human instance you cannot hide from... Remember the "We have it all", pronounced by "45"? Maybe he simply told a FACT?
