Metadata

A JSON dictionary and a pointer to a Token.
class latest.ipv8.attestation.identity.metadata.Metadata(token_pointer: bytes, serialized_json_dict: bytes, private_key: latest.ipv8.types.PrivateKey | None = None, signature: bytes | None = None)

Bases: latest.ipv8.attestation.signed_object.AbstractSignedObject

A JSON dictionary and a pointer to a Token.

Metadata does not and should not contain an index. Metadata does not and should not contain a reference to the public key (but is signed by one).

get_plaintext() → bytes

Serialized Metadata consists of a token pointer and serialized JSON.

classmethod unserialize(data: bytes, public_key: latest.ipv8.keyvault.keys.PublicKey, offset: int = 0) → Metadata

Unserialize metadata from the given bytes.

classmethod create(token: latest.ipv8.types.Token, json_dict: dict, private_key: latest.ipv8.types.PrivateKey) → Metadata

Create new metadata for a token from a JSON dict, signed using our key.

to_database_tuple() → tuple[bytes, bytes, bytes]

Get a representation of this Metadata as three byte strings (token hash, signature and json dictionary).

Returns:

the three byte strings for database insertion.

classmethod from_database_tuple(token_pointer: bytes, signature: bytes, serialized_json_dict: bytes) → Metadata

Create a Token from a three-byte-string representation (token hash, signature and json dictionary).

Parameters:

  • token_pointer – the hash of the Token.

  • signature – the signature over the plaintext Metadata.

  • serialized_json_dict – the serialized json dictionary of this Metadata.

__str__() → str

Convert this Metadata to human-readable format.
