How to contribute to EJBCA

The normal process for contribution patches is:

  • Contributors send patches, under the LGPLv2.1+ license, as pull requests. Creating an issue with short snippets of code is also accepted if you don’t want to make a pull request.
  • Include a JUnit test case for your change, it may be a simple addition to an existing test. If you do not know how to do this, ask us and we will help you.
  • Someone on the EJBCA core team will review them when there is time, and if needed suggest improvements.
  • If it is a useful and generic feature it will be integrated in EJBCA to be available in a later release.

Please follow these simple guidelines when submitting patches:

  • Keep the patch limited, only change the parts related to your patch. Do not change other lines, such as whitespace, adding line breaks to Java doc, etc. This makes patch review much more difficult.
  • Contributors are asked if they want to have their name and optional contact information listed on the contributors page.

For more information, refer to the EJBCA documentation on Getting Started with EJBCA Development.
