DerivedKey

class DerivedKey

Result of key derivation containing the derived cryptographic material.

IMPORTANT: This is a regular class (not data class) because:

  1. It contains mutable state that gets wiped via clear

  2. It should not be copied (copies would share mutable arrays)

  3. Hash code changes after clearing (breaks collections)

Security:

  • Call clear when done to wipe all keys from memory

  • Private, public, and chain code are ALL wiped

  • After clearing, this instance should not be used again
