JSON Web Key

JSON Web Key.

class josepy.jwk.JWK(**kwargs: Any)

JSON Web Key.

cryptography_key_types: Tuple[Type[Any], ...] = ()

Subclasses should override.

required: Sequence[str] = NotImplemented

Required members of public key’s representation as defined by JWK/JWA.

thumbprint(hash_function: Callable[[], cryptography.hazmat.primitives.hashes.HashAlgorithm] = <class 'cryptography.hazmat.primitives.hashes.SHA256'>) → bytes

Compute JWK Thumbprint.

https://tools.ietf.org/html/rfc7638

Returns

bytes

abstract public_key() → josepy.jwk.JWK

Generate JWK with public key.

For symmetric cryptosystems, this would return self.

classmethod load(data: bytes, password: Optional[bytes] = None, backend: Optional[Any] = None) → josepy.jwk.JWK

Load serialized key as JWK.

Parameters

• data (str) – Public or private key serialized as PEM or DER.

• password (str) – Optional password.

• backend – A PEMSerializationBackend and DERSerializationBackend provider.

Raises

errors.Error – if unable to deserialize, or unsupported JWK algorithm

Returns

JWK of an appropriate type.

Return type

JWK

class josepy.jwk.JWKOct(**kwargs: Any)

Symmetric JWK.

fields_to_partial_json() → Dict[str, str]

Serialize fields to JSON.

public_key() → josepy.jwk.JWKOct

Generate JWK with public key.

For symmetric cryptosystems, this would return self.

class josepy.jwk.JWKRSA(*args: Any, **kwargs: Any)

RSA JWK.

Variables

key – RSAPrivateKey or RSAPublicKey wrapped in ComparableRSAKey

public_key() → josepy.jwk.JWKRSA

Generate JWK with public key.

For symmetric cryptosystems, this would return self.

fields_to_partial_json() → Dict[str, Any]

Serialize fields to JSON.

class josepy.jwk.JWKEC(*args: Any, **kwargs: Any)

EC JWK.

Variables

key – EllipticCurvePrivateKey or EllipticCurvePublicKey wrapped in ComparableECKey

fields_to_partial_json() → Dict[str, Any]

Serialize fields to JSON.

public_key() → josepy.jwk.JWKEC

Generate JWK with public key.

For symmetric cryptosystems, this would return self.
