hash_hmac

在php中hash_hmac函數就能將HMAC和一部分哈希加密算法相結合起來實現HMAC-SHA1 HMAC-SHA256 HMAC-MD5等等算法。函數介紹如下： string hash_hmac(string $algo, string $data, string $key, bool $raw_output = false) algo：要使用的哈希算法名稱，可以是上述提到的md5,sha1等 data：要進行哈希運算的消息，也就是需要加密的明文。 key：使用HMAC生成信息摘要是所使用的密鑰。 raw_output：該參數為可選參數，默認為false，如果設為true，則返回原始二進制數據表示的信息摘要，否則返回16進制小寫字符串格式表示的信息摘要（註意是16進制數，而非簡單的字母加數字）。另外：如果algo參數指定的不是受支持的算法，將返回false
