You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: ubiquiti.rb
    path of file: ./repos/metasploit-framework/lib/msf/core/auxiliary
    
    the code of the file until where you have to start completion: # -*- coding: binary -*-

require 'bson'
require 'zip'

module Msf

  module Auxiliary::Ubiquiti

    def decrypt_unf
    
    def extract_and_process_db(db_path)
      f = nil
      Zip::File.open(db_path) do |zip_file|
        # Handle entries one by one
        zip_file.each do |entry|
          # Extract to file
          next unless entry.name == 'db.gz'

          print_status('extracting db.gz')
          gz = Zlib::GzipReader.new(entry.get_input_stream)
          f = gz.read
          gz.close
          break
        end
      end
      f
