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

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

• Loading certificates from PEM strings/files/cryptography object into a pydantic model including all x509 v3 extensions
• Checking revocation of certificates using OCSP with CRL fallback

Documentation is available at: https://pki-tools.fulder.dev

Quickstart

Install

pip install pki-tools

Usage

Loading certificate

from pki_tools import Certificate

cert_pem = """
-----BEGIN CERTIFICATE-----
<CERT_PEM_BYTES>
-----END CERTIFICATE-----
"""

cert = Certificate.from_pem_string(cert_pem)

Loading chain

from pki_tools import Chain

issuer_cert_pem = """
-----BEGIN CERTIFICATE-----
<ISSUER_CERT_PEM_BYTES>
-----END CERTIFICATE-----
"""

chain = Chain.from_pem_string(issuer_cert_pem)

Checking revocation using OCSP with CRL fallback

The following example is using the cert and chain from the examples above

from pki_tools import is_revoked

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