tiny_ca.ca_factory.utils.afile_loader module

class tiny_ca.ca_factory.utils.afile_loader.AsyncCAFileLoader(ca_cert_path, ca_key_path, ca_key_password=None, logger=None)[source]

Bases: object

Loads a CA certificate and private key from PEM files on the local filesystem.

Responsibility: file reading and PEM deserialisation only. Does not generate certificates, manage sessions, or perform any cryptographic operations beyond deserialisation.

On construction the loader: 1. Validates that both paths point to existing, regular files with

permitted extensions (see ALLOWED_CERT_EXTENSIONS).

  1. Deserialises the CA certificate and private key from PEM.

  2. Extracts CertificateInfo from the CA certificate’s Subject.

After successful construction all three ICALoader properties are available and will not change for the lifetime of the instance.

Parameters:

  • ca_cert_path (str | Path) – Path to the PEM-encoded CA certificate file.

  • ca_key_path (str | Path) – Path to the PEM-encoded CA private key file.

  • ca_key_password (str | bytes | None) – Optional password protecting the private key. A str value is encoded to bytes using UTF-8 before being passed to the cryptography library. None means the key is unencrypted.

  • logger (Logger | None) – Logger instance for diagnostic messages. Falls back to DEFAULT_LOGGER when None.
