crypto AES 加密 解密

1、aes加密解密说明

aes是对称加密算法

md5是摘要算法,不算是加密,主要用来对信息一致性和完整性校验。是不可逆的。

2、示例代码

<!DOCTYPE html>
<html lang="zh">

    <head>
        <meta charset="UTF-8" />
        <meta name="viewport" content="width=device-width, initial-scale=1.0" />
        <meta http-equiv="X-UA-Compatible" content="ie=edge" />
        <title>crypto 加密解密算法</title>
    </head>

    <body>
        <script src="https://cdn.bootcss.com/crypto-js/3.1.9/crypto-js.min.js"></script>
        <script type="text/javascript">
            //加密
            function encrypt(content, key) {

                if(typeof content === 'object') {

                    return CryptoJS.AES.encrypt(JSON.stringify(content), key).toString()
                }

                return CryptoJS.AES.encrypt(content.toString(), key).toString()
            }
            //解密
            function decrypt(content, key) {

                try {

                    return JSON.parse(CryptoJS.AES.decrypt(content, key).toString(CryptoJS.enc.Utf8))
                } catch(e) {

                    return CryptoJS.AES.decrypt(content, key).toString(CryptoJS.enc.Utf8)
                }

            }
            console.log(encrypt('abcabcabcabcabcabcabcabcabcabcabcabcabc', 'mfg'))
            console.log(decrypt(encrypt('abcabcabcabcabcabcabcabcabcabcabcabcabc', 'mfg'), 'mfg'))
        </script>
    </body>

</html>
