 === Credentials handling [[credentials]]
 Credentials needed to access SSH-based storages should be passed over to the pipelines (both for up- and download) as pipelines parameters. Basically each DLS pipelines can be extended by tasks to handle those parameters and convert them into connections that can be used in the remainings of the pipeline. The code for that can be found in <a href='dags/conn_deco.py'>+dags/conn_deco.py+</a>.
