JSON Web Key.

class acme.jose.jwk.JWK(**kwargs)[source]

Bases: acme.jose.json_util.TypedJSONObjectWithFields

JSON Web Key.

cryptography_key_types = ()

Subclasses should override.

required = NotImplemented

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

thumbprint(hash_function=<class 'cryptography.hazmat.primitives.hashes.SHA256'>)

Compute JWK Thumbprint.

Returns bytes:
public_key()

Generate JWK with public key.

For symmetric cryptosystems, this would return self.

classmethod load(data, password=None, backend=None)

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
