What
Add new API for parsing CPEs (pontos.cpe)
It follows the spec at https://nvlpubs.nist.gov/nistpubs/Legacy/IR/nistir7695.pdf very closely and implements all their escaping. Just the conversion to percent-encoded strings for quoting non-alphanumeric characters is using
urllib.parser.quote
andunquote
which support additional quoting besides specified in the CPE document.Why
Allow to parse and analyze CPE information from their v2.2 and v2.3 string representations. It's also possible to convert a v2.2 CPE representation into a v2.3 and vice versa. We need this for being able to use the new NIST CVE and CPE API.
