PKI Certificate Client in Python

Jump to bottom
Endi S. Dewata edited this page Jan 21, 2021 · 1 revision

Overview

This page provides an example of a PKI certificate client in Python.

All PKI Python modules are installed at $PYTHON_LIB/pki. The pem file is used for client auth. The pem file is created from the p12 cert file.

Initial Setup

from pki.client import PKIConnection
from pki.cert import CertClient

connection = PKIConnection(hostname="localhost", port="8443")
connection.set_authentication_cert("/tmp/auth_cert.pem")

client = CertClient(connection)

Enrolling a user certificate using the CertClient

# Create a dictionary that stores values required for certificate enrollment
inputs = {}

# Set the cert_request_type
inputs['cert_request_type'] = 'crmf'

# Set the base64 encoded string of the crmf request generated to attribute cert_request
inputs['cert_request'] = """-----BEGIN CERTIFICATE REQUEST-----

"""

#Set the values for subject name attributes UID, Email, Common Name
inputs['sn_uid'] = 'test12345'
inputs['sn_e'] = '[email protected]')
inputs['sn_cn'] = 'TestUser')

# Create, submit and approve the enrollment request
cert_data_objects = client.enroll_cert('caUserCert', inputs)

# Since the caUserCert profile is used in the example the cert_data_objects list contains only one element.
cert_data = cert_data_objects[0]

# Print the certificate information
print('Serial Number: ' + cert_data.serial_number)
print('Issuer: ' + cert_data.issuer_dn)
print('Subject: ' + cert_data.subject_dn)
print('Status: ' + cert_data.status)
print('Not Before: ' + cert_data.not_before)
print('Not After: ' + cert_data.not_after)
print('Encoded: ')
print(cert_data.encoded)
print("Pretty print format: ")
print(cert_data.pretty_print)

The result for the above code snippet, using a CA which already has 7 approved certificates, looks like:

List the certificates

cert_search_request = CertSearchRequest(serial_from='6', status='VALID')
cert_data_infos = client.list_certs(cert_search_request)

for cert_data_info in cert_data_infos:
    print("Serial Number: " + cert_data_info.serial_number)
    print("Subject DN: " + cert_data_info.subject_dn)
    print("Status: " + cert_data_info.status)

The output for the above code snippet looks like this:

Serial Number: 0x6
Subject DN: CN=PKI Administrator,[email protected],O=redhat.com Security Domain
Status: VALID

Serial Number: 0x7
Subject DN: CN=TestServer,O=Red Hat Inc.,L=Raleigh,ST=NC,C=US
Status: VALID

Serial Number: 0x8
Subject DN: UID=test12345,[email protected],CN=TestUser
Status: VALID

Serial Number: 0x9
Subject DN: CN=TestServer,O=Red Hat Inc.,L=Raleigh,ST=NC,C=US
Status: VALID

Get a specific certificate

cert_data = client.get_cert('9')

# Print the certificate information
print('Serial Number: ' + cert_data.serial_number)
print('Issuer: ' + cert_data.issuer_dn)
print('Subject: ' + cert_data.subject_dn)
print('Status: ' + cert_data.status)
print('Not Before: ' + cert_data.not_before)
print('Not After: ' + cert_data.not_after)
print('Encoded: ')
print(cert_data.encoded)
print("Pretty print format: ")
print(cert_data.pretty_print)

The result for the above code snippet, using a CA which already has 8 approved certificates, looks like:

Serial Number: 0x9
Issuer: CN=CA Signing Certificate,O=redhat.com Security Domain
Subject: CN=TestServer,O=Red Hat Inc.,L=Raleigh,ST=NC,C=US

Generating a list of certificate requests

cert_request_infos = client.list_requests(request_status='success', start = '6')
for cert_request_info in cert_request_infos:
    print("Request ID: " + cert_request_info.get_request_id())

    print("Status: " + cert_request_info.request_status)
    print("Certificate ID: " + cert_request_info.cert_id)

The output for the code snippet above looks like:

Request ID: 6
Type: enrollment
Request Status: complete
Certificate ID: 0x6

Request ID: 7
Type: enrollment
Request Status: complete
Certificate ID: 0x7

Request ID: 8
Type: enrollment
Request Status: complete
Certificate ID: 0x8

Request ID: 9
Type: enrollment
Request Status: complete
Certificate ID: 0x9

Getting information for a specific certificate request

cert_request_info = client.get_request('6')

print("Request ID: " + cert_request_info.get_request_id())
print("Type: " + cert_request_info.cert_request_type)
print("Status: " + cert_request_info.request_status)
print("Operation Result: " + cert_request_info.operation_result)
print("Certificate ID: " + cert_request_info.cert_id)

Output:

Request ID: 6
Type: enrollment
Request Status: complete
Operation Result: success
Certificate ID: 0x6
