pki.util.keys¶

Utility methods for private key generation and hash algorithm retrieval.

Classes¶

`AutoGenPkiKeyAlgorithm`	The key algorithms supported by the AutoGenPKI.
`KeyGenerator`	Utility class for generating private keys.
`CryptographyUtils`	Utilities methods for cryptography corresponding to Trustpoint models.

TypeGuard function that narrows down the public key type.

class pki.util.keys.AutoGenPkiKeyAlgorithm(*args, **kwds)[source]¶

Bases: django.db.models.TextChoices

The key algorithms supported by the AutoGenPKI.

to_public_key_info()[source]¶

Gets the corresponding public key info for the key algorithm.

class pki.util.keys.KeyGenerator[source]¶

Utility class for generating private keys.

static generate_private_key_for_public_key_info(key_info)[source]¶

Generates a private key for a public key info.

static generate_private_key(domain)[source]¶

Generates a key pair of the type corresponding to the domain model.

Parameters:: domain (pki.models.domain.DomainModel) – The domain to consider.
Returns:: The generated private key / key pair serializer.
Return type:: trustpoint_core.serializer.PrivateKeySerializer

class pki.util.keys.CryptographyUtils[source]¶

Utilities methods for cryptography corresponding to Trustpoint models.

static get_hash_algorithm_for_private_key(private_key)[source]¶

Gets a suitable hash algorithm for a given private key.

Parameters:: private_key (trustpoint_core.crypto_types.PrivateKey) – The private key to consider.
Returns:: The hash algorithm to use.
Return type:: cryptography.hazmat.primitives.hashes.HashAlgorithm

pki.util.keys.is_supported_public_key(public_key)[source]¶

TypeGuard function that narrows down the public key type.

Parameters:: public_key (Any) – The loaded public key to check if it is supported.
Returns:: True if it is supported, False otherwise.
Return type:: TypeGuard[trustpoint_core.crypto_types.PublicKey]
