Expand description

Key types that support “hierarchical deterministic” key derivation

Required Methods§

source

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§

source

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.

source

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.
