Java HmacSHA1算法详解编程语言

    public static String hmacSha1(String src, String key) { 
        try { 
            SecretKeySpec signingKey = new SecretKeySpec(key.getBytes("utf-8"), "HmacSHA1"); 
            Mac mac = Mac.getInstance("HmacSHA1"); 
            mac.init(signingKey); 
            byte[] rawHmac = mac.doFinal(src.getBytes("utf-8")); 
            return Hex.encodeHexString(rawHmac); 
        } catch (Exception e) { 
            throw new RuntimeException(e); 
        } 
    }
