public static String hashHmacSha1(String value, String key) {
	try {

		return new String(hexBytes, "UTF-8");
	} catch (Exception e) {

		SecretKeySpec signingKey = new SecretKeySpec(keyBytes, "HmacSHA1");
		Mac mac = Mac.getInstance("HmacSHA1");
		mac.init(signingKey);
		return mac.doFinal(value.getBytes());
	} catch (Exception e) {
		throw new RuntimeException(e);
	}
}
public static void main(String[] args) {
	System.out.println( hashHmacSha1( "hello world", "secret" ) );
