Signature

# Key Parameters of Request Header:

Parameters Description
RT-AccessCode the identifier of the requester, provided by RedteaHub, is used in the request header when calling the API.
RT-Timestamp the second timestamp of the current time, which is valid for 10 minutes and is used in the request header.
RT-RequestID the UUID generated in each request, the same RequestID can only be used once (in the request header)
RT-Signature packet signature result, which is case insensitive and used in request header

# Signature Calculation:

# Calculation by HMACSHA256:

  • signData = Timestamp + RequestID + AccessCode + RequestBody
  • signature = HMACSHA256(signData, SecretCode)
//Java signature algorithm implementation

public static String HMACSHA256(String data, String secretCode) throws Exception {
        Mac sha256HMAC = Mac.getInstance("HmacSHA256");
        SecretKeySpec secretKey = new SecretKeySpec(secretCode.getBytes("UTF-8"), "HmacSHA256");
        sha256HMAC.init(secretKey);
        byte[] array = sha256HMAC.doFinal(data.getBytes("UTF-8"));
        StringBuilder sb = new StringBuilder();
        for (byte item : array) {
            sb.append(Integer.toHexString((item & 0xFF) | 0x100).substring(1, 3));
        }
        return sb.toString().toUpperCase();
    }
