password hash calculation

[hellt]

On Discord there was an interesting thread of how to configure password hashes to supply them in the configuration.

The blog post can delve into the following topics

1. plain text vs hash password input
2. different hashing algos (sha512, argon2, yescrypt)
3. calculating hashes off box vs on box (with examples)
