---

how to run

decode_x509

decode x509 using openssl x509 -text

python parser.py decode_x509 $SECRET_NAME -n $NAMESPACE

this should show the details of the x509 certificate

get_tls

getting expiry date for previous tls

python parser.py get_tls $SECRET_NAME -n $NAMESPACE

result should looks like this

SECRET                           NAMESPACE                        DATEBEFORE                       CN
secret_name                      default                          2099-02-13 01:29:05              *.a.fake.domain

get_tls_all

 python parser.py get_tls_all

result should looks like this

SECRET                               NAMESPACE                            DATEBEFORE                           CN
