# Keyed Hash
hasher = Blake3::Hasher.new("I have a key")
hasher.update("h")

hasher.update("e")
hasher.finalize
# => "01cd3c62e5fd3fbf708f16cca9f5f9dadcbbc6e0c8687c9156dca43a2950a863"

# Derive Key
Blake3.derive_key("Context", "Input Key")
# => "e911a37d54141f6ed5a0c0b6168796a3533eff87c6fb40bdc56436f7c00f763f"
