Argon2 as password-hashing function in Camunda
Introduction On the new version of the Camunda Engine Platform (7.7) the user passwords, which are stored in the database, are by default hashed with a SHA-2 family algorithm. Before the passwords are hashed, they are concated with an individual random generated salt for each user, to prevent dictionary and rainbow table attacks. For someone who needs a more secure hashing algorithm Camunda introduce a new API, which allows to customize and exchange the default hashing algorithm. In this blog post I will present this customization and will use argon2 as hashing algorithm. Argon2 is a password-hashing function 1, which is considered as state of the art and also won the Password Hashing Competition at the end of 2015 2….

Integrating Camunda and Drupal

For the record, Drupal is an Open Source CMS powering a large number of the top websites available on the Internet. Therefore it is reasonable to assume that the combination of Camunda and Drupal is a possible scenario.

Conway’s game of life
The holidays are upon us, time for a lighter kind of blog post: Conways’s game of life on a Raspberry Pi. Conways game of life can be modelled by the following bpmn and dmn: In order to see what is happening the Raspberry Pi was hooked up to a 8×8 LED matrix (can be bought e.g at Adafruit together with the Raspberry Pi 3, breadboard and jumper wires). The LED matrix is driven by a simple program written in Go that receives the information which LED to light or dim through a socket connection from the Camunda engine. The final result can be seen below: Video showing Conway’s game of life in action The process accepts three parameters: rows, cols,…

Batch Operations with Camunda 7.6
Camunda 7.6 got released few weeks ago and it comes with many new exciting features. One of them is the extended Batch Operation feature and within this post I am gonna tell you what you can do with it and why it is so useful. Before I outline some really good use cases for Batch Operations let’s have a look what the concept actually means. Batch In general, batch processing is a concept in which a number of jobs is executed without manual intervention.

How to chain decisions with DRDs
Happy Birthday DMN DMN has proven to be a very popular and well adopted standard for describing and executing business rules. It’s uptake among Camunda users alone has been very impressive, especially considering it’s a standard that’s only about a year old. It’s popularity has given us the perfect excuse to implement even more elements of the standard. In fact since we first started to support it, we’ve been asked about when we intend to implement DRDs (Decision Requirements Diagram). With the release of Camunda 7.6 we’ve done just that. This post is simply a way of showing how to use DRDs and is especially relevant if you’re already familiar with DMN tables. Assignment Use Case DMN has become a…
