Usage

Encoding and decoding

from ib1.directory.extensions import encode_roles, decode_roles
...

cert_builder = (
    x509.CertificateBuilder()
    .subject_name(subject)
    .issuer_name(issuer)
    .public_key(private_key.public_key())
    .serial_number(x509.random_serial_number())
    .not_valid_before(datetime.utcnow())
    .not_valid_after(datetime.utcnow() + timedelta(days=365))
)

cert_builder = encode_roles(cert_builder, roles)

cert = cert_builder.sign(private_key, hashes.SHA256(), default_backend())

roles = decode_roles(cert)

Require a role

from ib1 import directory
...
    cert = directory.parse_cert(quoted_certificate_from_header)
    try:
        directory.require_role(
            "https://registry.core.ib1.org/scheme/perseus/role/carbon-accounting",
            cert,
        )
    except directory.CertificateRoleError as e:
        raise HTTPException(
            status_code=401,
            detail=str(e),
        )
...

Commands for generating certificates

The included cli can generate CA and issuer key certificate pairs suitable for signing client and server CSR requests in the IB1 Trust Framework.

Generate a CA key and certificate

Usage: ib1-directory create-ca [OPTIONS]

  Generate a server signing CA key and certificate and an issuer key and
  certificate pair signed by the CA then saves all files to disk

Options:
  -u, --usage [signing|client|server]  Choose signing, server or client CA
  -c, --country TEXT           Country to use for certificate generation
  -s, --state TEXT             State to use for certificate generation
  -f, --framework TEXT         Framework this certificate is for
  --help                       Show this message and exit.

eg. to create a server CA key and certificate for the Core Trust Framework:

poetry run ib1-directory create-ca -u server -f Core

Create test client and server certficates
