Key types that support "hierarchical deterministic" key derivation

Required methods

fn derived_key<T>(&self, t: T, cc: ChainCode) -> (Self, ChainCode) where
    T: SigningTranscript, 

Derive key with subkey identified by a byte array presented via a SigningTranscript, and a chain code.

Provided methods

fn derived_key_simple<B: AsRef<[u8]>>(
    &self,
    cc: ChainCode,
    i: B
) -> (Self, ChainCode)

Derive key with subkey identified by a byte array and a chain code. We do not include a context here becuase the chain code could serve this purpose.

fn derived_key_simple_rng<B, R>(
    &self,
    cc: ChainCode,
    i: B,
    rng: R
) -> (Self, ChainCode) where
    B: AsRef<[u8]>,
    R: RngCore + CryptoRng, 

Derive key with subkey identified by a byte array and a chain code, and with external ranodmnesses.
