Oh, reading the page at https://www.hivesystems.io/blog/are-your-passwords-in-the-green, they're assuming your password hashing algorithm is just plain MD5 without any hash iteration, claiming is "2018 cybersecurity practices". @Tutanota, please tell me are not hashing your users' passwords with plain MD5 without any hash iteration? Because Unix has iterated its password hashing function since 7th edition Unix, 25 iterations of modified DES: https://en.wikipedia.org/wiki/Crypt_(C)#Traditional_DES-based_scheme. That was in 1979. The password encryption approach Hive is suggesting has been known to be bad practice since 1979. When PHK implemented md5crypt for BSD in the 90s, it used 1000 iterations of MD5. A single iteration is not 2018 practice.

(Some people surely did commit this error in building their systems.)

Aren't actually proposing "a hacker" with a hundred times as much power as the entire Bitcoin network; are proposing to rent eight A100 GPUs from Amazon AWS which they say would get 523 billion hashes per second, the which is 16 million times less compute than the Bitcoin network. At this speed 2^90 hashes would take 75 million years, not the 3 weeks they state, the which is correct for 2^60.
