Issue

According to Misc | Node Crypto, the timingSafeEqual function should be supported by nodejs_compat.

However, when logging import crypto from "node:crypto";, you see

{
	DiffieHellman: [Function: DiffieHellman],
	DiffieHellmanGroup: [Function: DiffieHellmanGroup],
	createDiffieHellman: [Function: createDiffieHellman],
	createDiffieHellmanGroup: [Function: createDiffieHellmanGroup],
	getDiffieHellman: [Function: getDiffieHellman],
	KeyObject: [class KeyObject],
	PublicKeyObject: [class PublicKeyObject extends AsymmetricKeyObject],
	PrivateKeyObject: [class PrivateKeyObject extends AsymmetricKeyObject],
	SecretKeyObject: [class SecretKeyObject extends KeyObject],
	generateKey: [Function: generateKey],
	generateKeyPair: [Function: generateKeyPair],
	generateKeyPairSync: [Function: generateKeyPairSync],
	generateKeySync: [Function: generateKeySync],
	createPrivateKey: [Function: createPrivateKey],

	Hmac: [Function: Hmac],
	createHash: [Function: createHash],
	createHmac: [Function: createHmac],
	getHashes: [Function: getHashes],

	hkdfSync: [Function: hkdfSync],
	pbkdf2: [Function: pbkdf2],
	pbkdf2Sync: [Function: pbkdf2Sync],
	getCiphers: [Function: getCiphers],
	getCurves: [Function: getCurves],
	secureHeapUsed: [Function: secureHeapUsed],
	setEngine: [Function: setEngine],
	timingSafeEqual: undefined,
	getFips: [Function: getFips],
	setFips: [Function: setFips],
	fips: [Getter/Setter],
	subtle: SubtleCrypto {},
	webcrypto: Crypto { subtle: SubtleCrypto {} }
}

where it appears that timingSafeEqual is defined as undefined...

Probably

needs to be

export const timingSafeEqual = crypto.subtle.timingSafeEqual;

For some reason, node crypto and web crypto define it in different places, I remember this from miniflare 2 😅
