Notes

Fingerprinted Vaultwarden server Version 2022.12.0.

• <link rel="icon" type="image/png" sizes="32x32" href="images/favicon-32x32.png"/>

$ favicon-32x32.png
favicon-32x32.png: PNG image data, 32 x 32, 8-bit gray+alpha, non-interlaced
$ md5 favicon-32x32.png
MD5 (favicon-32x32.png) = 9e8ba456e7e39ea364cc538959813719

• <link rel="icon" type="image/png" sizes="16x16" href="images/favicon-16x16.png"/>

$ file favicon-16x16.png
favicon-16x16.png: PNG image data, 16 x 16, 8-bit gray+alpha, non-interlaced
$ md5 favicon-16x16.png
MD5 (favicon-16x16.png) = 86157069c9574d4c75b907e614d6a521

• favicon.ico matches Bitwarden's hash 2f0df01346ace9afb440288feeb5d974 so it was excluded from the fingerprint

I made a suggestion on wording for the service description. Fix that, and ship it? Sorry I'm still getting kinda used to how github review workflow actually works.
