Chrome: Cannot read cookies from Chrome 96

[nlowe]

• OS: Windows 10 21H1 (OS Build 19043.1348)
• Browser: 96.0.4664.93 (Official Build) (64-bit)
• Kooky Version: v0.0.0-20210408152652-87b89e95f98f

On windows, it seems Chrome 96+ has moved the cookie store to %LOCALAPPDATA%\Google\Chrome\User Data\Default\Network\Cookies, which is a SQLite database that seems to contain cookie metadata and encrypted cookie values. However, when I point kooky at this database file, it can't seem to decrypt the cookies stored here (I first noticed this a few days ago when my template generator for Advent of Code stopped being able to download input files):

package main

import (
    "fmt"
    "net/http"
    "os"
    "path/filepath"
    "runtime"

    "github.com/zellyn/kooky"
    "github.com/zellyn/kooky/chrome"
)

func chromeCookiePath() (string, error) {
    if p, set := os.LookupEnv("CHROME_PROFILE_PATH"); set {
        return filepath.Join(p, "Cookies"), nil
    }

    if runtime.GOOS == "windows" {
        localAppData, err := os.UserCacheDir()
        return filepath.Join(localAppData, "Google", "Chrome", "User Data", "Default", "Network", "Cookies"), err
    }

    return "", fmt.Errorf("chrome cookie path for GOOS %s not implemented, set CHROME_PROFILE_PATH instead", runtime.GOOS)
}
func main() {
    cookiePath, err := chromeCookiePath()
    if err != nil {
        panic(err)
    }

    cookies, err := chrome.ReadCookies(cookiePath, kooky.Valid, kooky.Name("session"), kooky.Domain(".adventofcode.com"))
    if err != nil {
        panic(err)
    }

    req, err := http.NewRequest(http.MethodHead, "https://adventofcode.com/2021/leaderboard/self", nil)
    if err != nil {
        panic(err)
    }

    sessionToken := cookies[0].HTTPCookie()
    req.AddCookie(&sessionToken)

    resp, err := http.DefaultClient.Do(req)
    if err != nil {
        panic(err)
    }

    fmt.Println(resp.Status)
}

This panics with:

As far as I know, for some reason kooky cannot decrypt the default profile cookie (google chrome). However, it decrypts other profiles fine.
