And here’s a fun fact: Did you know that Python was named after the British comedy series “Monty Python’s Flying Circus”? Go figure! 😄

Program Code – Python for Advanced Public Key Infrastructure (PKI)

from cryptography.hazmat.backends import default_backend
from cryptography import x509
from cryptography.hazmat.primitives import hashes, serialization
from cryptography.hazmat.primitives.asymmetric import rsa
from datetime import datetime, timedelta

# Generate private key for Root CA
root_private_key = rsa.generate_private_key(
    public_exponent=65537,
    key_size=4096,
    backend=default_backend()
)

# Write our Root CA private key to disk in PEM format
with open('root_private_key.pem', 'wb') as f:
    f.write(root_private_key.private_bytes(
        encoding=serialization.Encoding.PEM,
        format=serialization.PrivateFormat.PKCS8,
        encryption_algorithm=serialization.NoEncryption()
    ))

# Generate a root certificate
root_public_key = root_private_key.public_key()
builder = x509.CertificateBuilder()
builder = builder.subject_name(x509.Name([
    # Provide various details about who we are.
    x509.NameAttribute(x509.oid.NameOID.COUNTRY_NAME, u'US'),
    x509.NameAttribute(x509.oid.NameOID.STATE_OR_PROVINCE_NAME, u'California'),

    x509.NameAttribute(x509.oid.NameOID.COMMON_NAME, u'My Company Root CA'),
]))
builder = builder.issuer_name(x509.Name([
    # Our issuer is ourself.
    x509.NameAttribute(x509.oid.NameOID.COUNTRY_NAME, u'US'),
    x509.NameAttribute(x509.oid.NameOID.STATE_OR_PROVINCE_NAME, u'California'),
    x509.NameAttribute(x509.oid.NameOID.LOCALITY_NAME, u'San Francisco'),
    x509.NameAttribute(x509.oid.NameOID.ORGANIZATION_NAME, u'My Company'),
    x509.NameAttribute(x509.oid.NameOID.COMMON_NAME, u'My Company Root CA'),
]))
builder = builder.not_valid_before(datetime.utcnow())
builder = builder.not_valid_after(datetime.utcnow() + timedelta(days=10*365)) # Valid for 10 years
builder = builder.serial_number(x509.random_serial_number())
builder = builder.public_key(root_public_key)
builder = builder.add_extension(
    x509.BasicConstraints(ca=True, path_length=None), critical=True,
)
# Self-sign our certificate
root_certificate = builder.sign(
    private_key=root_private_key, algorithm=hashes.SHA256(),
    backend=default_backend()
)

# Write our root certificate out to disk in PEM format
with open('root_certificate.pem', 'wb') as f:
    f.write(root_certificate.public_bytes(serialization.Encoding.PEM))

print('Root CA key and certificate have been generated!')

Code Output:

The program will not output textual results since it is creating files, but if executed successfully, the last print statement would output ‘Root CA key and certificate have been generated!’

Code Explanation:

This Python script is dedicated to setting up an Advanced Public Key Infrastructure (PKI) system. Here’s how it gets the job done:

1. Imports the necessary modules from the Cryptography library for creating encryption and serialization functions.
2. Generates a private key for the Root Certificate Authority (CA) using the RSA algorithm, and a key size of 4096 bits.
3. Saves the private key to a file in PEM format.
4. Creates a builder object for the upcoming root certificate, using x509.CertificateBuilder.
5. Sets up the subject name and issuer name with extensive details such as country, state/province, locality, organization, and a common name (since it’s a root CA, the issuer and subject are the same).
6. Assigns the validity period of the certificate, which is 10 years in this script.
7. Generates a random serial number for the certificate.
8. Adds the public key to the certificate builder.
9. Constructs the BasicConstraints extension, marking this certificate as a CA certificate.
10. Self-signs the certificate with the previously generated private key.
11. Saves the root certificate to a file in PEM format.
12. Finally, prints a confirmation message saying that both key and certificate have been generated.
