gpru/stealth-keys API

Source-derived exports, parameter and result types, public methods and source links.

This reference is generated from the checked-out TypeScript exports. Types and signatures describe the package contract; source presence does not establish deployment or service availability. Error expressions below are direct throws, not an exhaustive list of failures from dependencies.

Source module. See the reference index for package import boundaries and verification scope.

deriveOwnerGpruDnaKeyV1

Recover the one-time private key for a DNA using the owner’s stable scan secret. The Node creates the ephemeral and one-time public keys; it never receives this secret or the owner’s scan secret.

Import from @trustlink/tsn-sdk. Implementation, line 91.

deriveOwnerGpruDnaKeyV1(params: { dna: Uint8Array; ephemeralPublicKey: Uint8Array; oneTimePublicKey: Uint8Array; scanSecretKey: Uint8Array; }): GpruDnaOwnerKeyV1

Direct failure expressions:

new Error("GPRU scan secret key is not a canonical nonzero Solana ElGamal scalar")
new Error("GPRU DNA key does not match the Node-derived one-time public key")
