Parameters:value – value to attempt to convert to bytes
Returns:tuple containing boolean indicating whether user_id was stored as bytes and uuid value as bytes or the original value
classmethod base64_encode(s)[source]

Encode a URL-safe string.

Return type:six.text_type

Compress UUID formatted strings to bytes.

Parameters:uuid_string – uuid string to compress to bytes
Returns:a byte representation of the uuid
classmethod create_arguments_apply(**kwargs)[source]

Check the arguments to see if they apply to this payload variant.

Returns:True if the arguments indicate that this payload class is needed for the token otherwise returns False.
Return type:bool
classmethod disassemble(payload)[source]

Disassemble an unscoped payload into the component data.

The tuple consists of:

(user_id, methods, system, project_id, domain_id,
 expires_at_str, audit_ids, trust_id, federated_info,
 access_token_id, app_cred_id)
  • methods are the auth methods.
  • federated_info is a dict contains the group IDs, the identity provider ID, the protocol ID, and the federated domain ID

Fields will be set to None if they didn’t apply to this payload type.

Parameters:payload – this variant of payload
Returns:a tuple of the payloads component data

class keystone.token.token_formatters.TokenFormatter[source]

Bases: object

Packs and unpacks payloads into tokens for transport.

create_token(user_id, expires_at, audit_ids, methods=None, system=None, domain_id=None, project_id=None, trust_id=None, federated_info=None, access_token_id=None, app_cred_id=None)[source]

Given a set of payload attributes, generate a Fernet token.

classmethod creation_time(fernet_token)[source]

Return the creation time of a valid Fernet token.

crypto

Return a cryptography instance.

You can extend this class with a custom crypto @property to provide your own token encoding / decoding. For example, using a different cryptography library (e.g. python-keyczar) or to meet arbitrary security requirements.

This @property just needs to return an object that implements encrypt(plaintext) and decrypt(ciphertext).

pack(payload)[source]

Pack a payload for transport as a token.

Return type:six.text_type
classmethod restore_padding(token)[source]

Restore padding based on token size.

Parameters:token (six.text_type) – token to restore padding on
Returns:token with correct padding
unpack(token)[source]

Unpack a token, and validate the payload.

Return type:six.binary_type
validate_token(token)[source]

Validate a Fernet token and returns the payload attributes.
