How to: password hashing
you can hash passwords  before putting them into config files / providing them as arguments; see [`--help-pwhash`](https://copyparty.eu/cli/#pwhash-help-page) for all the details

`--ah-alg argon2` enables it, and if you have any plaintext passwords then it'll print the hashed versions on startup so you can replace them

optionally also specify `--ah-cli` to enter an interactive mode where it will hash passwords without ever writing the plaintext ones to disk

the default configs take about 0.4 sec and 256 MiB RAM to process a new password on a decent laptop

when generating hashes using `--ah-cli` for docker or systemd services, make sure it is using the same `--ah-salt` by:
* inspecting the generated salt using `--show-ah-salt` in copyparty service configuration
* setting the same `--ah-salt` in both environments

> ⚠️ if you have enabled `--usernames` then provide the password as `username:password` when hashing it, for example `ed:hunter2`
