publicKeyFromSeed

Signature

publicKeyFromSeed(seed: Seed): Uint8Array

Purpose

Derives a 32-byte FourQ public key from a Seed. The seed is hashed with KangarooTwelve (K12) to produce the private scalar, then the public key is computed as a scalar multiplication on the FourQ curve. The result is deterministic — the same seed always produces the same public key.

import { publicKeyFromSeed } from "@qubic.org/crypto"
import { toSeed } from "@qubic.org/types"

const seed = toSeed("aaaaabbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb")
const publicKey: Uint8Array = publicKeyFromSeed(seed)
// publicKey.length === 32

Parameters

Returns

Uint8Array — 32-byte FourQ public key.
