pokemongo-encryption-sharp

Managed C# code for the Pokemon Go API request signature encryption (port of "encrypt.c")

---

Project contains a fully managed port of the encrypt.c code as well as a p/invoke wrapper for the native encrypt.dll binaries.

The managed lib is a PCL that targets .NET 4.5.1, ASP.NET Core, Xamarin.iOS/Android/Mac.

Both libs should work on about any mono platform. However, only the 32bit & 64bit encrypt.dll Windows binaries are included.

Sample usage

byte[] input = System.Text.Encoding.UTF8.GetBytes("Sample input data..");
byte[] iv = new byte[32];
new Random().NextBytes(iv);

// using managed lib
byte[] output = PokemonGoEncryptSharp.Util.Encrypt(input, iv);

// using native wrapper lib
byte[] output = PokemonGoEncryptNative.Util.Encrypt(input, iv);
