Hash this string using the SHA-256 algorithm.

deviceFingerprintPayload =      
"<ssid|app.id|device.uuid|mobile_number|customer_reference|timestamp>"MessageDigest digest = MessageDigest.getInstance("SHA-256");
byte[] deviceFingerprint = digest.digest(deviceFingerprintPayload.getBytes(StandardCharsets.UTF_8));

Send the timestamp within the headers.
