Witness

Transaction witness.

class pycardano.witness.VerificationKeyWitness(vkey: 'Union[VerificationKey, ExtendedVerificationKey]', signature: 'bytes')

Bases: ArrayCBORSerializable

vkey: VerificationKey | ExtendedVerificationKey

signature: bytes

property json_type: str

Return the class name of the CBORSerializable object.

This property provides a default string representing the type of the object for use in JSON serialization.

Returns:: The class name of the object.
Return type:: str

property json_description: str

Return the docstring of the CBORSerializable object’s class.

This property provides a default string description of the object for use in JSON serialization.

Returns:: The docstring of the object’s class.
Return type:: str

classmethod from_primitive(values: list | tuple) → VerificationKeyWitness

Restore a primitive value to its original class type.

Parameters:

cls (ArrayBase) – The original class type.
values (List[Primitive]) – A list whose elements are CBOR primitives.

Returns:

Restored object.

Return type:

ArrayBase

Raises:

DeserializeException – When the object could not be restored from primitives.

to_shallow_primitive() → list | tuple: Convert to a shallow primitive representation.
