If you have questions or issues, please let us know [here][bitmono_issues]. Download the latest version of BitMono [here][bitmono_releases].\n\nYou can also use BitMono as an engine to build custom obfuscators. It is built using dependency injection (DI) using [Autofac][autofac_repo] and follows the latest C# best practices.\n\n\u003cp align=\"center\"\u003e\n\u003cimg src=\"https://raw.githubusercontent.com/sunnamed434/BitMono/main/resources/images/preview/before-after.png\"\n  alt=\"Before and after obfuscation preview by BitMono\"\u003e\n\u003c/p\u003e\n\n\u003cp align=\"center\"\u003e\n\u003cimg src=\"https://raw.githubusercontent.com/sunnamed434/BitMono/main/resources/images/preview/before-after-2.png\"\n  alt=\"Before and after obfuscation preview by BitMono 2\"\u003e\n\u003c/p\u003e\n\n\u003cp align=\"center\"\u003e\n\u003cimg src=\"https://raw.githubusercontent.com/sunnamed434/BitMono/main/resources/images/preview/CLI.png\"\n  alt=\"CLI\"\u003e\n\u003c/p\u003e\n\n\u003cp align=\"center\"\u003e\n\u003cimg src=\"https://raw.githubusercontent.com/sunnamed434/BitMono/main/resources/images/preview/configuration.png\"\n  alt=\"Configuration\"\u003e\n\u003c/p\u003e\n\n## Usability\n\nBitMono breaks the most popular tools using just one packer, such as:\n- dnSpy;\n- dnlib;\n- AsmResolver;\n- MonoCecil;\n- ILSpy;\n- PEBear;\n- DetectItEasy;\n- CFF Explorer\n- Perhaps, some dumpers?\n- and many, many more...\n\nSo, if you will add more protection to the file, I think it would seem like total magic. :D\n\n## Documentation\n\nRead the **[docs][bitmono_docs]** to read protection, functionality, and more.\n\n## How your app will look since BitMono obfuscation - just in a few words\n* Looks like C++ application but is an actual C# application;\n* Crash of decompilers when analyzing types;\n* Broken decompilers;\n* Broken IL Code;\n* Invisible types;\n* No code\n\n## Features\n\n* StringsEncryption\n* **[UnmanagedString][unmanagedstring_source]** (based on existing protection)\n* **[BitDotNet][bitdotnet_source]** (based and improved on existing protection)\n* **[BitMethodDotnet][bitmethoddotnet_source]** (based and improved on existing protection)\n* **[DotNetHook][dotnethook_source]** (based on existing protection)\n* CallToCalli\n* ObjectReturnType\n* NoNamespaces\n* FullRenamer\n* AntiDebugBreakpoints\n* AntiDecompiler\n* BitDecompiler (fixed version of BitDotNet for newer Unity Versions)\n* BitDateTimeStamp\n* BitMono\n* BillionNops\n* AntiDe4dot\n* AntiILdasm\n* and you can integrate existing/make own feature ;)\n\n## Usage\n\n### Download\n\nTo download the latest release of BitMono, follow these steps:\n\n1. Go to the [Latest BitMono Release][bitmono_latest_release].\n2. Select and download the archive file that matches the Target Framework of the application you want to protect. Here are some examples:\n\n- **Targeting .NET 8**: If your target file is built for .NET 8, download:\n  `BitMono-v0.25.3+e64e54d3-CLI-net8.0-win-x64.zip`\n\n- **Targeting .NET Standard**: If your target file is built for .NET Standard, you can use either BitMono for .NET Framework or .NET 8:\n  `BitMono-v0.25.3+e64e54d3-CLI-net8.0-win-x64.zip`\n\n- **Targeting .NET Framework**: If your target file is built for .NET Framework, download:\n  `BitMono-v0.25.3+e64e54d3-CLI-net462-win-x64.zip`\n\n- **Targeting Mono or Unity Engine Runtime**: If your target file is built for .NET Framework and runs on Mono or Unity, use the .NET Framework version:\n  `BitMono-v0.25.3+e64e54d3-CLI-net462-win-x64.zip`\n\n\u003e **Note:** Be sure to select the correct version of BitMono that matches your Target Framework. Using the wrong version could result in compatibility issues, however, if that works ok anyway or if you know what you're doing, you can ignore it.\n\n### Pre-Require\n\nEnable one of the protection in `protections.json` file: Set `Enabled` to `true`.\n\n### Using CLI\n\n`BitMono.CLI \u003cpath to file\u003e/drag-and-drop`\n\nAlways drop dependencies in `libs` directory in the same path where `file` for obfuscation is located\n\nYour obfuscation directory structure will look something like this:\n```\nspecially_created_folder_for_obfuscation/\n├─ your_app.exe\n└─ libs/\n  ├─ ImportantLibrary.dll\n  ├─ SuperImportantLibrary.dll\n  └─ ...\n```\n\nCopy all libraries (.dll) from the building application folder and paste them into the `libs` directory (if it doesn't exist yet create it), or even create the libs directory yourself with a custom name for example - `myLibs`, and then specify it in BitMono, however, if you will use `libs` then by default BitMono looking for a `libs` directory, so it will save your time.\n\n### Using CLI Commands\n\n```console\n  -f, --file         Required. Set file path.\n\n  -l, --libraries    Set libraries path.\n\n  -o, --output       Set output path.\n\n  --help             Display this help screen.\n\n  --version          Display version information.\n```\n\nBasic example\n```console\n$ BitMono.CLI -f C:\\specially_created_folder_for_obfuscation/your_app.exe -l specially_created_folder_for_obfuscation/libs\n```\n\nIn case when you already have a directory with the name `libs` (specially_created_folder_for_obfuscation\\libs) BitMono will catch it automatically, so, you don't need to specify it anymore, but you can in case if you made another directory with `libs` somewhere on the disk or even just for \"visibility\".\n```console\n$ BitMono.CLI -f C:\\specially_created_folder_for_obfuscation/your_app.exe\n```\n\nSpecify custom `libs` directory\n```console\n$ BitMono.CLI -f C:\\specially_created_folder_for_obfuscation/your_app.exe -l C:\\mythings\\obfuscation\\superLibsDirectory\n```\n\nSpecify file, libs and output. If output directory doesn't exist BitMono will create it automatically and even open it on the top of the screen, if you want you can disable opening of the directory on the of top of the screen in `obfuscation.json` - and set `OpenFileDestinationInFileExplorer` to false.\n```console\n$ BitMono.CLI -f C:\\specially_created_folder_for_obfuscation/your_app.exe -l C:\\mythings\\obfuscation\\superLibsDirectory -o C:\\specially_created_folder_for_obfuscation/output\n```\n\nWant more?

Be careful using some protections because some might work on .NET Framework only, some on .NET (Core) only, some on all frameworks, some on Mono only - if the protection is unique to its platform/framework you will get a notification about that.\n\n| Framework      | Version |\n|----------------|---------|\n| .NET           | 9.0     |\n| .NET           | 8.0     |\n| .NET           | 7.0     |\n| .NET           | 6.0     |\n| .NET Framework | 462     |\n| netstandard    | 2.0     |\n| netstandard    | 2.1     |\n\nCredits\n-------\n\n**[JetBrains][jetbrains_rider]** has kindly provided licenses for their JetBrains Rider IDE to the contributors of BitMono.
