NVDlib is a Python library that allows you to interface with the NIST National Vulnerability Database (NVD), pull vulnerabilities (CVEs), and Common Platform Enumeration (CPEs) into easily accessible objects.

• Search the NVD for CVEs using all parameters allowed by the NVD API (recently updated to utilize version 2 of the API). Including search criteria such as CVE publish and modification date, keywords, severity, score, or CPE name.
• Search CPE names by keywords, CPE match strings, or modification dates. Then pull the CVE ID's that are relevant to those CPEs.
• Retrieve details on individual CVEs, their relevant CPE names, and more.
• Built in rate limiting according to NIST NVD recommendations.
  Get an API key (https://nvd.nist.gov/developers/request-an-api-key) to allow for a delay argument to be passed. Otherwise it is 6 seconds between requests by default.

$ pip install nvdlib

>>> import nvdlib
>>> r = nvdlib.searchCVE(cveId='CVE-2021-26855')[0]
>>> print(r.v31severity + ' - ' + str(r.v31score))
CRITICAL - 9.8
>>> print(r.descriptions[0].value)
Microsoft Exchange Server Remote Code Execution Vulnerability This CVE ID is unique from CVE-2021-26412,

This is my first attempt at creating a library while utilizing all my Python experience from classes to functions.
