+Node style HMACs for use in the browser, with native HMAC functions in node. API is the same as HMACs in node:
+
+```js
+var createHmac = require('create-hmac')
+var hmac = createHmac('sha224', Buffer.from('secret key'))
+hmac.update('synchronous write') //optional encoding parameter
+hmac.digest() // synchronously get result with optional encoding parameter
+
+hmac.write('write to it as a stream')
+hmac.end() //remember it's a stream
+hmac.read() //only if you ended it as a stream though
+```
