CPE2_2 class

class cpe.cpe2_2.CPE2_2(cpe_str, *args, **kwargs)[source]

Implementation of version 2.2 of CPE specification.

A CPE Name is a percent-encoded URI with each name starting with the prefix (the URI scheme name) ‘cpe:’.

The distinct parts are:

  • Hardware part: the physical platform supporting the IT system.

  • Operating system part: the operating system controls and manages the IT hardware.

  • Application part: software systems, services, servers, and packages installed on the system.
