Toucan

Java implementation of LifeHash

Toucan is a Java implementation of the LifeHash hash visualization algorithm. It is a direct port of the reference C++/C implementation by Wolf McNally. Toucan requires a minimum of Java 17.

Setup

Toucan is hosted in Maven Central and can be added as a dependency with the following:

implementation('com.sparrowwallet:toucan:0.9.0')

Usage

A LifeHash is represented by the LifeHash.Image class, which can be created as follows:

import com.sparrowwallet.toucan.*;
import java.awt.image.BufferedImage;

public class Main {
    public static void main(String[] args) {
        LifeHash.Image lifeHashImage = LifeHash.makeFromUTF8("Hello World", LifeHashVersion.VERSION2, 1, false);
        BufferedImage awtImage = LifeHash.getBufferedImage(lifeHashImage);
    }
}

Testing

Toucan has a small testsuite ported from the C++ implementation. The tests can be run with:

./gradlew test
