We want to change the encryption method of exported data to GPG. The third-party software provider that is picking up the files needs to test their implementation of automatic processing, so we have to provide a test file for them. We can run the exporter and just write the column headers to a file.

Acceptance Criteria:

• The recipient's public GPG key is present on the machine creating the export files
• The nightly CSV exports are compressed and then encrypted using GPG
• Formerly used encryption keys are removed from the ansible-vault
• The respective user's home directory contains a folder called data_test.
• The test folder contains an encrypted file for the third-party to test.
