Added support for Argon2 hashing support for the `ADMIN_TOKEN` instead
of only supporting a plain text string.
The hash must be a PHC string which can be generated via the `argon2`
CLI **or** via the also built-in hash command in Vaultwarden.
You can simply run `vaultwarden hash` to generate a hash based upon a
password the user provides them self.
Added a warning during startup and within the admin settings panel is
the `ADMIN_TOKEN` is not an Argon2 hash.
Within the admin environment a user can ignore that warning and it will
not be shown for at least 30 days. After that the warning will appear
again unless the `ADMIN_TOKEN` has be converted to an Argon2 hash.
I have also tested this on my RaspberryPi 2b and there the `Bitwarden`
preset takes almost 4.5 seconds to generate/verify the Argon2 hash.
Using the `OWASP` preset it is below 1 second, which I think should be
fine for low-graded hardware. If it is needed people could use lower
memory settings, but in those cases I even doubt Vaultwarden it self
would run. They can always use the `argon2` CLI and generate a faster hash.
When a non sqlite database is used, loading the admin interface fails
because the backup button is not generated.
This PR is solves it by checking if the elements are valid.
Also made some other changes and fixed some eslint errors.
Showing `_post` errors is better now.
Update jquery to latest version.
Fixes#3166
- Removed `unsafe-inline` for javascript from CSP.
The admin interface now uses files instead of inline javascript.
- Modified javascript to work not being inline.
- Run eslint over javascript and fixed some items.
- Added a `to_json` Handlebars helper.
Used at the diagnostics page.
- Changed `AdminTemplateData` struct to be smaller.
The `config` was always added, but only used at one page.
Same goes for `can_backup` and `version`.
- Also inlined CSS.
We can't remove the `unsafe-inline` from css, because that seems to
break the web-vault currently. That might need some further checks.
But for now the 404 page and all the admin pages are clear of inline scripts and styles.
