而我之前玩的就是ASP代码。有一天我需要用到对象存储，但是要用对象存储就需要对请求URL进行加密。大家都知道ASP已经不更新了，要达到这样的加密根本就不行。因此我就找到了前端加密库Crypto-JS。加密效果杠杠的，顺利解决加密任务。
使用方法：
使用前先引用加密库Crypto-JS
/**
* message ：需要加密的字符串或数组
* miwen ：已经加密的密文
* key ：自己设置的密钥
*/
var hash = CryptoJS.MD5(message);
var hash = CryptoJS.SHA1(message);
var hash = CryptoJS.SHA256('message');
var hmac = CryptoJS.HmacMD5(message, key);
var hmac = CryptoJS.HmacSHA1(message, key);
var hmac = CryptoJS.HmacSHA256(message, key);
//base64加密
var base64String = CryptoJS.enc.Base64.stringify(message);
//base64解密
var wordArray = CryptoJS.enc.Base64.parse(miwen);对象存储使用示例：
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title></title>
<script type="text/javascript" src="crypto-js.js" ></script>
</head>
<body>
<p id="demo"></p>
<script>
function getSignature(accessId, secretKey, verb, ctMd5, ctType, date, resource) {
var message = verb + '\n'
+ ctMd5 + '\n'
+ ctType + '\n'
+ date + '\n'
+ '' + resource;
var secretMessage = CryptoJS.enc.Base64.stringify(CryptoJS.HmacSHA256(message, secretKey));
//secretMessage = encodeURIComponent(secretMessage);
//secretMessage = secretMessage.replace('\+', '%20');
return secretMessage;
}
var accessId = 'fbfa832dee2b4347869f726c6cacfcf7',
secretKey= '495567f8becd48765719371335f9d472',
verb = 'GET',
ctMd5 = '',
ctType = '',
date = 'Wed, 9 Aug 2017 12:42:00 GMT',
resource = '/';
var signature = getSignature(accessId, secretKey, verb, ctMd5, ctType, date, resource);
document.getElementById("demo").innerHTML = signature;
</script>
</body>
</html>
