Struct sn_dbc::MainKey

impl MainKey

pub fn new(secret_key: SecretKey) -> Self

pub fn secret_key(&self) -> &SecretKey

Get the secret key.

pub fn public_address(&self) -> PublicAddress

This is the static public address which is shared with others, and to which payments can be made by getting a new unique identifier for a Dbc to be created.

pub fn sign(&self, msg: &[u8]) -> Signature

Sign a message with the main key.

pub fn derive_key(&self, index: &DerivationIndex) -> DerivedKey

Derive the key - the DerivedKey - corresponding to a DbcId which was also derived using the same DerivationIndex.

When someone wants to send tokens to the PublicAddress of this MainKey, they generate the id of the Dbc - the DbcId - that shall hold the tokens. The recipient of the tokens, is the person/entity that holds this MainKey.

The created Dbc contains the derivation index that was used to generate that very DbcId.

When passing the derivation index to this function (fn derive_key), a DerivedKey is generated corresponding to the DbcId. This DerivedKey can unlock the Dbc of that DbcId, thus giving access to the tokens it holds. By that, the recipient has received the tokens from the sender.

pub fn to_bytes(&self) -> Vec<u8>

Represent as bytes.

pub fn random() -> Self

pub fn random_from_rng(rng: &mut impl RngCore) -> Self

Create a randomly generated MainKey.

pub fn random_derived_key(&self, rng: &mut impl RngCore) -> DerivedKey
