identityToPublicKey

Converts a 60-character Qubic identity string to a 32-byte FourQ public key for use in TCP requests and contract functions.

Signature

identityToPublicKey(identity: Identity): Uint8Array

Purpose

Converts an Identity string to a 32-byte public key. Use this when you need to pass a public key to a TCP request or a contract function — those APIs work with raw bytes, not the string encoding.

import { identityToPublicKey } from "@qubic.org/crypto"
import { toIdentity } from "@qubic.org/types"

const pk = identityToPublicKey(toIdentity("CFBMEMZOIDEXQAUXYYSZIURADQLAPWPMNJXQSNVQZAHYVOPYUKKJBJUCTVJL"))
// pk: Uint8Array (32 bytes)

Parameters

Name	Type	Description
`identity`	`Identity`	60-character uppercase identity string

Returns

Uint8Array — 32-byte FourQ public key.

Throws

InvalidIdentityError — if the identity string is not 60 uppercase characters.
