Fork note

go install cmd/kooky/kooky.gokooky --help
Reaching into browser-specific, vaguely documented, possibly concurrently modified cookie stores to pilfer cookies is a bad idea. Since you've arrived here, you're almost certainly going to do it anyway. Me too. And if we're going to do the Wrong Thing, at least let's try to Do it Right.
Package kooky contains routines to reach into cookie stores for Chrome, Firefox, Safari, ... and retrieve the cookies.
It aspires to be pure Go (I spent quite a while making go-sqlite/sqlite3 work for it).
It also aspires to work for all major browsers, on all three major platforms.
Status
Basic functionality works on Windows, MacOS and Linux. Some functions might not yet be implemented on some platforms. The API is currently not expected to be at all stable.
PRs more than welcome.
TODOs
- Make it work on Windows. (Look at this and this to learn how to decrypt.)
- Handle rows in Chrome's cookie DB with other than 14 columns (?)
Example usage
Any Browser - Cookie Filter Usage
package main
import (
"fmt"
"github.com/newnoetic/kooky"
_ "github.com/newnoetic/kooky/allbrowsers" // register cookie store finders!
)
func main() {
// uses registered finders to find cookie store files in default locations
// applies the passed filters "Valid", "DomainHasSuffix()" and "Name()" in order to the cookies
cookies := kooky.ReadCookies(kooky.Valid, kooky.DomainHasSuffix(`google.com`), kooky.Name(`NID`))
for _, cookie := range cookies {
fmt.Println(cookie.Domain, cookie.Name, cookie.Value)
}
}
Chrome on macOS
package main
import (
"fmt"
"log"
"os"
"github.com/newnoetic/kooky/chrome"
)
func main() {
dir, _ := os.UserConfigDir() // "/<USER>/Library/Application Support/"
cookiesFile := dir + "/Google/Chrome/Default/Cookies"
cookies, err := chrome.ReadCookies(cookiesFile)
if err != nil {
log.Fatal(err)
}
for _, cookie := range cookies {
fmt.Println(cookie)
}
}
Safari
package main
import (
"fmt"
"log"
"os"
"github.com/newnoetic/kooky/safari"

Overview ¶
Package kooky contains routines to reach into cookie stores for various browsers and retrieve the cookies.
Example (ChromeSimpleMacOS) ¶
package main
import (
"fmt"
"os"
"github.com/newnoetic/kooky/chrome"
)
// on macOS:
var cookieStorePath = "/Google/Chrome/Default/Cookies"
func main() {
// construct file path for the sqlite database containing the cookies
dir, _ := os.UserConfigDir() // on macOS: "/<USER>/Library/Application Support/"
cookieStoreFile := dir + cookieStorePath
// read the cookies from the file
// decryption is handled automatically
cookies, err := chrome.ReadCookies(cookieStoreFile)
if err != nil {
// TODO: handle the error
return
}
for _, cookie := range cookies {
fmt.Println(cookie)
}
}
Output:

Functions ¶
func ExportCookies ¶
ExportCookies() export "cookies" in the Netscape format.
curl, wget, ... use this format.
Example ¶
package main
import (
"os"
"github.com/newnoetic/kooky"
)
var cookieFile = `cookies.txt`
func main() {
var cookies = []*kooky.Cookie{{Domain: `.test.com`, Name: `test`, Value: `dGVzdA==`}}
file, err := os.OpenFile(cookieFile, os.O_RDWR|os.O_CREATE, 0644)
if err != nil {
// TODO: handle error
return
}
defer file.Close()
kooky.ExportCookies(file, cookies)
}
Output:
func FilterCookie ¶
FilterCookie() tells if a "cookie" passes all "filters".
func RegisterFinder ¶
func RegisterFinder(browser string, finder CookieStoreFinder)
RegisterFinder() registers CookieStoreFinder enabling automatic finding of cookie stores with FindAllCookieStores() and ReadCookies().
RegisterFinder() is called by init() in the browser subdirectories.
Types ¶
type Cookie ¶
type Cookie struct {
Domain string
Name string
Path string
Expires time.Time
Secure bool
HttpOnly bool
Creation time.Time
Value string
}
Cookie is the struct returned by functions in this package. Similar to http.Cookie.
func FilterCookies ¶
FilterCookies() applies "filters" in order to the "cookies".
Example ¶
package main
import (
"github.com/newnoetic/kooky"
_ "github.com/newnoetic/kooky/allbrowsers" // register cookiestore finders
)
var cookieName = `NID`
func main() {
cookies := kooky.ReadCookies() // automatic read
cookies = kooky.FilterCookies(
cookies,
kooky.Valid, // remove expired cookies
kooky.DomainContains(`google`), // cookie domain has to contain "google"
kooky.Name(cookieName), // cookie name is "NID"
kooky.Debug, // print cookies after applying previous filter
)
}
Output:
func ReadCookies ¶
ReadCookies() uses registered cookiestore finders to read cookies. Erronous reads are skipped.
Register cookie store finders for all browsers like this:
import _ "github.com/newnoetic/kooky/allbrowsers"
Or only a specific browser:
import _ "github.com/newnoetic/kooky/chrome"
Example (All) ¶
package main
import (
"fmt"
"github.com/newnoetic/kooky"
_ "github.com/newnoetic/kooky/allbrowsers" // This registers all cookiestore finders!
// _ "github.com/newnoetic/kooky/chrome" // load only the chrome cookiestore finder
)
func main() {
// try to find cookie stores in default locations and
// read the cookies from them.
// decryption is handled automatically.
cookies := kooky.ReadCookies()
for _, cookie := range cookies {
fmt.Println(cookie)
}
}
var _ struct{} // ignore this - for correct working of the documentation tool
Output:
func (Cookie) HTTPCookie ¶
HTTPCookie() returns an http.Cookie equivalent to this Cookie.
type CookieStore ¶
type CookieStore interface {
ReadCookies(...Filter) ([]*Cookie, error)
Browser() string
Profile() string
IsDefaultProfile() bool
FilePath() string
Close() error
}
CookieStore represents a file, directory, etc containing cookies.
Call CookieStore.Close() after using any of its methods.
func FindAllCookieStores ¶
func FindAllCookieStores() []CookieStore
FindAllCookieStores() tries to find cookie stores at default locations.
FindAllCookieStores() requires registered CookieStoreFinders.
Register cookie store finders for all browsers like this:
import _ "github.com/newnoetic/kooky/allbrowsers"
Or only a specific browser:
import _ "github.com/newnoetic/kooky/chrome"
Example ¶
package main
import (
"fmt"
"github.com/newnoetic/kooky"
_ "github.com/newnoetic/kooky/allbrowsers" // register cookiestore finders
)
var filters = []kooky.Filter{
kooky.Valid, // remove expired cookies
}
func main() {
cookieStores := kooky.FindAllCookieStores()
for _, store := range cookieStores {
// CookieStore keeps files/databases open for repeated reads
// close those when no longer needed
defer store.Close()
var filters = []kooky.Filter{
kooky.Valid, // remove expired cookies
}
cookies, _ := store.ReadCookies(filters...)
for _, cookie := range cookies {
fmt.Printf(
"%s\t%s\t%s\t%s\t%s\t%s\t%s\n",
store.Browser(),
store.Profile(),
store.FilePath(),
cookie.Domain,
cookie.Name,
cookie.Value,
cookie.Expires.Format(`2006.01.02 15:04:05`),
)
}
}
}
Output:
type CookieStoreFinder ¶
type CookieStoreFinder interface {
FindCookieStores() ([]CookieStore, error)
}
CookieStoreFinder tries to find cookie stores at default locations.
type Filter ¶
Filter is used for filtering cokies in ReadCookies() functions.
A cookie passes the Filter if Filter returns true.
Example (Regex) ¶
package main
import (
"fmt"
"regexp"
"github.com/newnoetic/kooky"
)
// example regex matching base64 strings
var reBase64 = regexp.MustCompile(`^(?:[A-Za-z0-9+/]{4})*(?:[A-Za-z0-9+/]{2}==|[A-Za-z0-9+/]{3}=|[A-Za-z0-9+/]{4})$`)
func main() {
var cookies = []*kooky.Cookie{{Name: `test`, Value: `dGVzdA==`}}
cookies = kooky.FilterCookies(
cookies,
ValueRegexMatch(reBase64), // filter cookies with the regex filter
// kooky.Debug, // print cookies after applying the regex filter
)
for _, cookie := range cookies {
fmt.Println(cookie.Value)
break // only first element
}
}
func ValueRegexMatch(re *regexp.Regexp) kooky.Filter {
return func(cookie *kooky.Cookie) bool {
return cookie != nil && re != nil && re.Match([]byte(cookie.Value))
}
}
Output: dGVzdA==
Debug prints the cookie.
Position Debug after the filter you want to test.
