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 because 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 randomnesses.
