Written by Christopher Zell on , under Integration category.
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.

How to chain decisions with DRDs

Written by Niall Deehan on , under DMN category.
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).

  • new groupId: org.camunda.bpm.extension.springboot and a new maven module structure
  • switch to Java 8
  • switch to Spring Boot 1.4.2
  • switch to Camunda BPM 7.6.0
