Could you clarify a little, by encryption do you mean encryption of process variables? If thats the case there is no built in encryption that I am aware of. I have implemented my own encryption in the past…
it’s more about whether the data which can be entered/uploaded
through the Camunda GUI are stored encrypted on a hard disk (or whatever).
If so, is there a standard encryption method and a padding procedure
(see in my first question) which is provided by Camunda?
Camunda does not write directly to the filesystem but uses a relational database for persistence. You should check the documentation of the database you use for an answer to your question.
