succeun / robohash4j

Robohash4j is port of robohash for java.

RoboHash

The source code for RoboHash.org.

It basically copy/pastes various robot pictures together, using bits from the SHA hash. It's not perfect, and not entirely secure, but it gives a good gut-check to "Hey, this SHA is wrong."

Usage

    import com.hihds.robohash4j.Robohash;
    
    String hash = "whatever-hash-you-want"
    byte[] pngImage = Robohash.assemble(ImageSet.ROBOHASH_SET1, hash.getBytes(), Format.PNG);
    Files.write(Paths.get("file.png"), pngImage);

Robosets

RoboHash comes with three image sets, named "ROBOHASH_SET1", "ROBOHASH_SET2", and "ROBOHASH_SET3". Specify which set you want in the assemble() method. Alternatively, specify the string "ROBOHASH_ANY", and RoboHash will pick an image set for you, based on the provided hash.

The "ROBOHASH_SET1" artwork was created by Zikri Kader. The ROBOHASH_SET2" artwork was created by Hrvoje Novakovic. The "ROBOHASH_SET3" artwork was created by Julian Peter Arias.

Disclaimer

OK, I'll admit I'm a crappy programmer. Compounding this, I wrote this code initially to be internal-only. It's ugly, and could be a LOT nicer.

Sorry about that.
