THIS PROJECT IS NO LONGER MAINTAINED.

SimplePatchTool is a general-purpose patcher library for standalone applications.

Support the Developer ☕

FEATURES

• written completely in C#
• supports repair patching as well as binary diff patching
• gives you complete control over where the patch files are stored (you can even host your files on Google Drive™)
• supports self patching (e.g. launcher patching itself)
• does not request admin permissions unless necessary
• supports encrypting/signing important patch files as an additional layer of security
• compatible with .NET Standard 2.0 (the optional XML signing module requires additional NuGet package(s)) and Mono 2.0 (according to official .NET Portability Analyzer)

Currently, this library is only tested on a 64-bit Windows 10 installment. Please note that SimplePatchTool is not yet battle tested thoroughly, so you may encounter unknown issues while integrating it into your projects. Don't hesitate to open an Issue when you encounter one!
