pki-tools 0.0.21

PKI tools for e.g. checking certificate CRL/OCSP revocation

PKI tools exposes a high level cryptography API for e.g.:

• checking revocation of certificates:
  • using CRL defined in the x509 CRL distribution points extension (https://datatracker.ietf.org/doc/html/rfc5280.html#section-4.2.1.13)
  • using OCSP defined in the x509 Authority Information Access extension (https://datatracker.ietf.org/doc/html/rfc5280.html#section-4.2.2.1)
• loading certificates from PEM format
• saving certificates to files
• reading certificates from files

Quickstart

Install

pip install pki-tools

Usage

Checking OCSP and CRL revocation

from pki_tools import is_revoked
from pki_tools.types import PemCert, Chain

cert_pem = """
-----BEGIN CERTIFICATE-----
<CERT_PEM_BYTES>
-----END CERTIFICATE-----
"""
issuer_cert_pem = """
-----BEGIN CERTIFICATE-----
<ISSUER_CERT_PEM_BYTES>
-----END CERTIFICATE-----
"""
chain = Chain.from_pem(issuer_cert_pem)

if is_revoked(PemCert(cert_pem), chain):
    print("Certificate Revoked!")
