hkd32 0.3.1

HMAC-based Hierarchical Key Derivation: deterministically derive a hierarchy of symmetric keys from initial keying material through repeated applications of the Hash-based Message Authentication Code (HMAC) construction. Optionally supports storing root derivation passwords as a 24-word mnemonic phrase (i.e. BIP39).
