Does not work with Node.js Web Crypto and UUID

[bkiac]

Maybe I'm doing something wrong but I can't get a UUID -> encrypt -> encode -> decode -> decrypt -> UUID flow working.

import crypto from 'crypto'
import {Encoder, Encrypter} from 'objectid64'

global.crypto = crypto.webcrypto

const encoder = new Encoder()

const key = await Encrypter.generateKey()
const encrypter = new Encrypter(key)

const uuid = crypto.randomUUID()
console.log(uuid) // 4874c42f-61e3-42c8-9a39-4007a81737e7

const binUuid = encoder.toBinUUID(uuid)
const encrypted = await encrypter.fromUUID(binUuid)
const encoded = encoder.fromBinUUID(encrypted)
console.log(encoded) // MxbKSQB-fuDtqUJayvuVCO

const decoded = encoder.toBinUUID(encoded)
const decrypted = await encrypter.toUUID(decoded)
const uuid2 = encoder.fromBinUUID(decrypted)
console.log(uuid2) // 4874c42f-61e3-42c8-9C3, uuid is not recovered in full

console.log(uuid === uuid2) // false

Node.js version: 16.17.1
objectid64 version: 3.2.1

The bug was in my code, it's unrelated to this package (or the Node.js Web Crypto implementation), this is the working code:

import crypto from 'crypto'
import {Encoder, Encrypter} from 'objectid64'

global.crypto = crypto.webcrypto

const uuidStringToBinary = (enc: Encoder, uuid: string): Uint8Array =>
  enc.toBinUUID(enc.fromUUID(uuid))
const uuidBinaryToString = (enc: Encoder, uuid: Uint8Array): string =>
  enc.toUUID(enc.fromBinUUID(uuid))

const encoder = new Encoder()

const key = await Encrypter.generateKey()
const encrypter = new Encrypter(key)

const uuid = crypto.randomUUID()

const binUuid = uuidStringToBinary(encoder, uuid)
const encrypted = await encrypter.fromUUID(binUuid)
const encoded = encoder.fromBinUUID(encrypted)

const decoded = encoder.toBinUUID(encoded)
const decrypted = await encrypter.toUUID(decoded)
const uuid2 = uuidBinaryToString(encoder, decrypted)

console.log(uuid === uuid2) // true
