This is a solution for a challenge that wants:

• Write a Python script that converts json files to xml, encrypts and transfers to a remote location.
• Solution should be prepared as two Docker images, 1st to send files, and 2nd to receive them.
• Pipeline: json -> XML -> encryption -> transfer -> decryption -> XML

This solution:

• Sender container:

  • Have a python script that:
    • Read json files from ./data_json/, converts it and save the XML files in ./data_xml/.
    • Read the XML files, encrypt the data and send to server using HTTP POST and json: {'file_name': 'encrypted_name', 'data': 'encrypted_data'}

• Server container:

  • Have a Flask app that:
    • Receives encrypted data via HTTP POST
    • Decrypts received data
    • Saves the in XML files in ./data_server/ using the same name as used in sender

To use:

• Clone this repo
• Puts the json files in ./data/data_json/
• Run docker-compose -up
• The sender XML files will be saved in ./data/data_xml/ (in plain text, the data is encrypted only when will be transfer)
• The XML files received and decrypted by the server will be saved in ./data/data_server/
