HMACpublic static String calculateRFC2104HMAC(String

data, String key)

{

SecretKeySpec signingKey = new SecretKeySpec(key.getBytes(), “HmacSHA1”);

Mac mac = Mac.getInstance(“HmacSHA1”);

mac.init(signingKey);

byte[] rawHmac = mac.doFinal(data.getBytes());

return Encoding.EncodeBase64(rawHmac);

}

Stateless

Don’t DDOS Yourself

• Use RESTful principles for correct status codes (5xx vs 4xx) so clients know when to rety.• Use correct headers:• Retry-After: 120
