NETBinaryCookie

A simple, independent Apple binarycookies format read-write package for .NET projects.

Makes Mac cookie forensics without limitations a breeze with .NET!

Supports parsing lists of cookies from an input binarycookies file or stream otherwise. Also supports writing those cookies back to disk or another stream.

Dependencies

The dependency graph for this package is kept intentionally minimal, and concerted effort has been made to keep it dependency-free.

Feedback

Please submit any bug reports, feature requests, or other concerns on the project's GitHub page (where you can also find a lot more juicy information about the binarycookies file format!).

Example Usage

Below demonstrates a very rudimentary usage of the read functions within this package.

At some later time, the to-be-implemented write functions will make modifying saved cookie stores much more viable.

using NETBinaryCookie; // ... var cookieJar = NETBinaryCookie.ReadFromFile(@"/Users/myuser/Documents/Cookies.binarycookies"); var mySpecificCookies = cookieJar.GetCookies( cookie => cookie.Domain.ToLower().Contains("github.")); // ... var cookiesAfterChristmas = cookieJar.GetCookies( cookie => cookie.Creation > new DateTime(2023, 12, 25)); foreach (var cookie in cookiesAfterChristmas) { Console.WriteLine(cookie); } // ... // If you're so inclined to do MORE than read the cookies file... cookieJar.AddCookie(new() { Creation = DateTime.Now, Expiration = DateTime.Now + TimeSpan.FromDays(5), Domain = ".xmit.xyz", Name = "HelloFromDotnet", Path = "/myurl", Value = "Hello, world!", Flags = new[] { NetBinaryCookie.CookieFlag.SamesiteLax, NetBinaryCookie.CookieFlag.Secure } }); cookieJar.Save();
