CoseKey

Utility functions for converting between COSE_Key and P256 public keys.

COSE_Key is the key format used in WebAuthn attestation objects, as defined in RFC 9053.

Examples

Below are some examples demonstrating common usages of the CoseKey module:

• Encoding a Public Key to COSE_Key

• Decoding a COSE_Key to Public Key

Encoding a Public Key to COSE_Key

import { CoseKey, P256 } from 'ox'
 
const { publicKey } = P256.createKeyPair()
 
const coseKey = CoseKey.fromPublicKey(publicKey)

Decoding a COSE_Key to Public Key

import { CoseKey, P256 } from 'ox'
 
const { publicKey } = P256.createKeyPair()
const coseKey = CoseKey.fromPublicKey(publicKey)
 
const publicKey2 = CoseKey.toPublicKey(coseKey)
