What are these directories and files in ~/Library/Application Support/Google/Chrome?

Question

Whilst looking for something else entirely, i stumbled across these, in Chrome's Application Support folder.

# syh @ h in ~/Library/Application Support/Google/Chrome/ZxcvbnData/1 [21:07:42]
$ l
total 1592
drwx------@ 11 syh  staff   352B Dec 19 21:06 .
drwx------@  3 syh  staff    96B Dec 19 21:06 ..
-rw-r--r--@  1 syh  staff    66B Oct 11 10:56 manifest.fingerprint

-rw-------@  1 syh  staff   160K Oct 11 10:56 us_tv_and_film.txt

It looks like some data that is being used by zxcvbn, which Chrome might be using. Does anyone know what Chrome is using this for?

This was tracked in Chromium bug 1104878 - Passwords: Add zxcvbn-cpp as third_party library.

This issue serves as a tracking bug to add zxcvbn-cpp [1] as a third_party library to Chromium. It is intended to be used for realistic password strength estimation within the Password Manager component.
