A lightweight, flexable and dependency free implementation of the Ksuid
A Ksuid is a particular match of Unique Identifier generation and Binary Encoding. It has a 4 byte timestamp, and 16 bytes of entropy, and encodes to a 27 character string.
The string is URL safe, and will be naturally sorted my date order.
This project is released on Maven Central.
You are welcome to clone and build, but please open PR's if there are bugs.
implementation 'com.kncept.ksuid:ksuid:1.0.1'
Just import the main class and off you go. You may need to write a little encoder/decoder function for a custom type if you wish to use this some sort of ORM, but this works excellently all the way from passing in on a URL, to saving in a database, and back again.
import com.kncept.ksuid.Ksuid;
...
System.out.println(new Ksuid());
I think the concept came from https://github.com/segmentio/ksuid. When I started using them, the java implementation I was using had some encoding / length bugs, so I wrote a partial implementation. Finally, I broke this out into its own open source project and finished it.
Disclaimer - there are probably implementations that work just fine, and don't have the encoding/decoding bugs. This is still being open sourced, as it's an extremely light implementation and includes support for multiple ways to use them.
If the library ever needs to be extended, submit a PR!
