KIM Care is a toolset to transfer files via the KIM component of the German Telematik-Infrastruktur using Apache NiFi.
The Apache NiFI processors were tested with KoPS 3.1.

Prerequisites:

• A local/remote NiFI service of a certain version is assummed.
• Maven should be installed locally to compile the processors.

Compile the processors with the following steps:

• Change both NiFi version entries in nifi-kim-*/pom.xml from 1.18.0 to your NiFi version.
• Run the following commands:

# Transceiver
cd uaux-kim-tx
mvn clean package
cd ..

# Receiver
cd uaux-kim-rx
mvn clean package
cd ..

• Retrieve the .nar processor files from uaux-kim-*/nifi-kim-*-nar/target/nifi-kim-*-nar-*.nar and place them into the lib folder of the NiFi instance.
• Restart the NiFi instance to load the processors.

Note: If you are using the KoPS simulator, make sure to virtually insert a valid crypto card to be able to successfully authenticate with SMTP/POP3.

Transmission: The KIMTX processor sends an incoming flow file to a KIM address as mail with attachment. Change the flow file filename attribute to define the file name of the attachment.
An example is given here:

The configuration can be as follows:

Receive: The KIMRX processor emits a flow file with the content of a received mail attachment. An example is given here:

The configuration can be as follows:
