Sigillum

Sigillum is a tool created to obfuscate / enrypt a payload. In Sigillum this process is called "Sealing". Sealing a payload with Sigillum will provide both the sealed payload as well as the desealing function in the programming language chosen by the user. Sigillum can be used to simplify the process of developing software with encrypted payloads, ranging from images, to text, to binaries.

How to use

Sigillum requires a payload the seal and a key to seal it with. If both are provided the standard seal algorithm will be RC4 and the output language will be C. Here follows an example of how to use Sigillum:

Windows

go run .\bin\main.go --payload "Sigillum is cool!" --key "secret"

Linux

go run ./bin/main.go --payload "Sigillum is cool!" --key "secret"

Choosing algorithm

To choose a specific algorithm for the sealing and desealing process. One can use the --seal switch:

Windows

go run .\bin\main.go --payload "Sigillum is cool!" --key "secret" --seal "AES"

Linux

go run ./bin/main.go --payload "Sigillum is cool!" --key "secret" --seal "AES"

Save output

A path to a file can also be used. Although with some files (like .png files or .jpg files), the seal can become quite substantial. Therefore it is recommended to use the --output switch to directly write the output to a file.

Windows

go run .\bin\main.go  --payload "Sigillum is cool!" --key "secret" --output out.c

Linux

go run ./bin/main.go  --payload "Sigillum is cool!" --key "secret" --output out.c

File as payload

If you want to use a file as a payload. There's a switch to also name the file once it has been desealed by the desealing algorithm. This switch is Which will provide a file as output. When a path is provided as the payload, Sigillum will also output the desealing function with the output of that function being a file. This can be achieved by using the --filename switch:

Windows

go run .\bin\main.go --payload "Sigillum is cool!" --key "secret" --filename "my_image.png"

Linux

go run ./bin/main.go --payload "Sigillum is cool!" --key "secret" --filename "my_image.png"

Usage in code

To implement Sigillum in your own code, make sure you have Golang installed. You can use Sigillum as follows:

import (
	"fmt"
	"github.com/0xAlcidius/Sigillum/sigillum"
)
 
func main() {
	seal, found := sigillum.Seal["RC4"]
	if !found {
		fmt.Printf("Seal function not found.")
		return
	}

	seal.ExecuteSeal([]byte("secret"), []byte("Sigillum is cool!"))
}

You can change "RC4" also for "XOR" or "AES" for example.

Installation

To install Sigillum to your machine simply clone the repository:

git clone <repo.git>

Make sure Golang is installed on your machine
