Returns

Description if standard ACME error or None.

Return type

class acme.messages.Status(name: str)[source]

ACME “status” field.

class acme.messages.HasResourceType[source]

Represents a class with a resource_type class parameter of type string.

class acme.messages.Directory(jobj: Mapping[str, Any])[source]

Directory.

class Meta(**kwargs: Any)[source]

property terms_of_service: str

classmethod register(resource_body_cls: Type[acme.messages.GenericHasResourceType]) Type[acme.messages.GenericHasResourceType][source]

Register resource.

to_partial_json() Dict[str, Any][source]

Partially serialize.

Following the example, partial serialization means the following:

assert isinstance(Bar().to_partial_json()[0], Foo)
assert isinstance(Bar().to_partial_json()[1], Foo)

# in particular...
assert Bar().to_partial_json() != ['foo', 'foo']
Raises

josepy.errors.SerializationError – in case of any serialization error.

Returns

Partially serializable object.

classmethod from_json(jobj: MutableMapping[str, Any]) acme.messages.Directory[source]

Deserialize a decoded JSON document.

Parameters

jobj – Python object, composed of only other basic data types, as decoded from JSON document. Not necessarily dict (as decoded from “JSON object” document).

Raises

josepy.errors.DeserializationError – if decoding was unsuccessful, e.g. in case of unparseable X509 certificate, or wrong padding in JOSE base64 encoded string, etc.

class acme.messages.Resource(**kwargs: Any)[source]

ACME Resource.

Variables

body (acme.messages.ResourceBody) – Resource body.

class acme.messages.ResourceWithURI(**kwargs: Any)[source]

ACME Resource with URI.

Variables

uri (str) – Location of the resource.

class acme.messages.ResourceBody(**kwargs: Any)[source]

ACME Resource Body.

class acme.messages.ExternalAccountBinding[source]

ACME External Account Binding

classmethod from_data(account_public_key: josepy.jwk.JWK, kid: str, hmac_key: str, directory: acme.messages.Directory) Dict[str, Any][source]

Create External Account Binding Resource from contact details, kid and hmac.

class acme.messages.Registration(**kwargs: Any)[source]

Registration Resource Body.

Variables
  • key (jose.JWK) – Public key.

  • contact (tuple) – Contact information following ACME spec, tuple of str.

  • agreement (str) –

classmethod from_data(phone: Optional[str] = None, email: Optional[str] = None, external_account_binding: Optional[Dict[str, Any]] = None, **kwargs: Any) acme.messages.GenericRegistration[source]

Create registration resource from contact details.

The contact keyword being passed to a Registration object is meaningful, so this function represents empty iterables in its kwargs by passing on an empty tuple.

to_partial_json() Dict[str, Any][source]

Modify josepy.JSONDeserializable.to_partial_json()

fields_to_partial_json() Dict[str, Any][source]

Modify josepy.JSONObjectWithFields.fields_to_partial_json()

Raises
  • errors.SerializationError – if field cannot be serialized

  • errors.Error – if field could not be found

to_partial_json() Dict[str, Any][source]

Partially serialize.

Following the example, partial serialization means the following:

assert isinstance(Bar().to_partial_json()[0], Foo)
assert isinstance(Bar().to_partial_json()[1], Foo)

# in particular...
assert Bar().to_partial_json() != ['foo', 'foo']
Raises
