"""Audit validity date of X509 crt/crl/csr.
This script is used to audit the validity date of crt/crl/csr used for testing.
It prints the information of X509 data whose validity duration does not cover
the provided validity duration. The data are collected from tests/data_files/
and tests/suites/*.data files by default.
It would print the information about X.509 data if the validity period of the
X.509 data didn't cover the provided validity period. The data are collected
