Not compatible with Deno, Bun

[c128128]

Thank you for your work. However, at the moment, this library is not compatible with Deno or Bun. Are there any plans to make it compatible?

@c128128 Could you please share errors or incompatibility you are seeing with Bun, for example?

When I import the library for use within Bun and execute

const appleRootCAs: Buffer[] = await loadAppleRootCertificates();
const enableOnlineChecks = true;
const environment = env.APPLE_ENVIRONMENT === "PRODUCTION"
? Environment.PRODUCTION
: Environment.SANDBOX;

const appAppleId = env.APPLE_ENVIRONMENT === "PRODUCTION"
? Number(env.APP_APPLE_ID)
: undefined; // appAppleId is required when the environment is Production

const verifier = new SignedDataVerifier(
appleRootCAs,
enableOnlineChecks,
environment,
bundleId,
appAppleId,
);

I get the error:

Error processing transaction: 40 |     constructor(appleRootCertificates, enableOnlineChecks, environment, bundleId, appAppleId) {
41 |         this.JWSRenewalInfoDecodedPayloadValidator = new JWSRenewalInfoDecodedPayload_1.JWSRenewalInfoDecodedPayloadValidator();

                                                                       ^

I assume this has something to do with the crypto module however Bun has support for node functions whether via

import { X509Certificate } from "node:crypto";
new X509Certificate(...);

or

import { X509Certificate } from "crypto"; although it is recommended to import via node:crypto

Any ideas why this might be happening?

Edit: Although the export exists it is marked as "missing" here https://bun.sh/docs/runtime/nodejs-apis#node-crypto , and when I try the following:

import { X509Certificate } from "node:crypto";

const certs = await loadAppleRootCertificates();

for (const cert of certs) {
    const x509cert = new X509Certificate(cert);
    console.log(x509cert);
}

I get the error: SyntaxError: Export named 'X509Certificate' not found in module 'crypto'. any thoughts on using a polyfill/library that doesn't depend on the node library itself and can bundle in support which doesn't call the node lib? Either that or should the transactions then be manually verified using JOSE/jsonwebtoken? If so can you provide an example of this?
