derivationPath property
Hierarchical-deterministic path to derive at. Where the custodian derives from a
seed, supplying the path makes the key reproducible from that seed; omitting it
leaves the choice to the custodian. MUST NOT be combined with internal: true,
which derives from no seed and records no path — a request carrying both is
contradictory and the maintainer SHOULD reject it.
Implementation
final String? derivationPath;
