      @Sirai, Please use below format to send multiple files

      ----BOUNDARY_STRING
      Content-Disposition: form-data; name="email";

      test@test.com
      ----BOUNDARY_STRING
      Content-Disposition: form-data; name="upload_test"; filename="myfile.pdf"
      Content-Type: text/octet-stream

      ENCRYPTED_FILE_CONTENT
