The user Id of the key.
def get_signer_key_user_id(signer_key_index: int) -> str: ... def set_signer_key_user_id(signer_key_index: int, value: str) -> None: ...
The user Id of the key. When a key is loaded this property is populated with the user Id associated with the key. This property may be set to load a key from the keyring. When this property is set the class will search the keyring for a key associated with the UserId specified.
When loading a key with multiple user Ids, this property will be populated with the UserId that was most recently added to the key. To discover all of the UserIds associated with a key query this property and key_other_user_ids after loading the key.
The UserId format is:
FirstName LastName (Comment) <Email>Not all values are required when selecting or generating a key, but at least FirstName or Email are required.
When using this property to select a key you may also specify the key's Id, or any of its subkeys' Ids, instead of a user Id. The class will then search for a key with a matching Id. This is helpful in situations where you do not have the UserId but still need to load the key, such as within the OpenPGP class's on_recipient_info event.
The signer_key_index parameter specifies the index of the item in the array. The size of the array is controlled by the signer_key_count property.
