Is there a way to do this with the native crypto module now?

function getSignatureKey(key, dateStamp, regionName, serviceName) {
        const kDate = CryptoJS.HmacSHA256(dateStamp, `AWS4${key}`);
        const kRegion = CryptoJS.HmacSHA256(regionName, kDate);
        const kService = CryptoJS.HmacSHA256(serviceName, kRegion);
        return CryptoJS.HmacSHA256('aws4_request', kService);
    }

i would expect not,N/crypto is bad with dynamic keys

yeah that's what I thought 😕

it expects the cryptographic key to be stored in the secret

maybe someday i can get rid of the last bits of cryptojs
