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."
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);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.

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.
