关于.net前端采用了CryptoJs插件，使用Aes模式加密数据，传到后台解密

前端代码：

    function formencode() {
        var KEY = CryptoJS.enc.Utf8.parse("1234567890123456");
        var IV = CryptoJS.enc.Utf8.parse('1234567890123456');
        var key = KEY;
        var iv = IV;
        var content = $("#txtSmsContent").val();

        var contentEncode = CryptoJS.enc.Utf8.parse(content);
        var encryptedContent = CryptoJS.AES.encrypt(contentEncode, key, {
            iv: iv,
            mode: CryptoJS.mode.ECB,
            padding: CryptoJS.pad.Pkcs7
        });
        var encryptContentBase64 = CryptoJS.enc.Base64.stringify(encryptedContent.ciphertext);
        $("#txtSmsContent").val(encryptContentBase64);
    }

后端代码：

        /// <summary>
        ///  AES 解密
        /// </summary>
        /// <param name="str">明文（待解密）</param>
        /// <param name="key">密文</param>
        /// <returns></returns>
        public static string AesDecrypt(string str, string key)
        {
            if (string.IsNullOrEmpty(str)) return null;
            Byte[] toEncryptArray = Convert.FromBase64String(str);

            RijndaelManaged rm = new RijndaelManaged
            {
                Key = Encoding.UTF8.GetBytes(key),
                Mode = CipherMode.ECB,
                Padding = PaddingMode.PKCS7
            };

            ICryptoTransform cTransform = rm.CreateDecryptor();
            Byte[] resultArray = cTransform.TransformFinalBlock(toEncryptArray, 0, toEncryptArray.Length);

            return Encoding.UTF8.GetString(resultArray);
        }

其中我采用的是ECB模式

 

 

后台加密，传到前台解密方法在下面

后台代码：

        /// <summary>
        ///  AES 加密
        /// </summary>
        /// <param name="str">明文（待加密）</param>
        /// <param name="key">密文</param>
        /// <returns></returns>
        public static string AesEncrypt(string str, string key)
        {
            if (string.IsNullOrEmpty(str)) return null;
            Byte[] toEncryptArray = Encoding.UTF8.GetBytes(str);

            RijndaelManaged rm = new RijndaelManaged
            {
                Key = Encoding.UTF8.GetBytes(key),
                Mode = CipherMode.ECB,
                Padding = PaddingMode.PKCS7
            };

            ICryptoTransform cTransform = rm.CreateEncryptor();
            Byte[] resultArray = cTransform.TransformFinalBlock(toEncryptArray, 0, toEncryptArray.Length);
            return Convert.ToBase64String(resultArray);
        }

前端代码：

function formencode() {
　　var src = $(this).text().trim();
　　var key = CryptoJS.enc.Utf8.parse("1234567890123456");
　　var decrypt = CryptoJS.AES.decrypt(src, key, {
　　mode: CryptoJS.mode.ECB,
　　padding: CryptoJS.pad.Pkcs7
　　});
　　$(this).text(decrypt.toString(CryptoJS.enc.Utf8));
    }
