1.5.2、javascript代碼

說(shuō)明：CBC模式前、后端需要確定偏移量的值，并且保持一致，這樣才能確保后端解密成功。

            }
            return CryptoJS.enc.Base64.stringify(encrypted.ciphertext);
        }
    });
</script>

1.6、.NET 后端代碼

1.6.1、定義公共的密匙字段

/// <summary>
/// //AES加密所需16位密匙
/// </summary>
private static readonly String strAesKey = "lucasnetLUCASNET";

/// <summary>
/// AES加密所需16位密匙向量
/// </summary>
private static readonly String strAesIv = "lucasnetLUCASNET";

1.6.2、封裝AES解密方法

/// <summary>
///  AES 解密
/// </summary>
/// <param name="str">密文（待解密）</param>
/// <returns></returns>
public string AesDecrypt(string str)
{
    if (string.IsNullOrEmpty(str)) return null;
    Byte[] toEncryptArray = Convert.FromBase64String(str);
    using (RijndaelManaged rm = new RijndaelManaged())
    {
        rm.Key = Encoding.UTF8.GetBytes(strAesKey);
        rm.IV = Encoding.UTF8.GetBytes(strAesIv);
        rm.Mode = CipherMode.CBC;
        rm.Padding = PaddingMode.PKCS7;
        rm.FeedbackSize = 128;
        ICryptoTransform encryptor = rm.CreateDecryptor(rm.Key, rm.IV);
        Byte[] resultArray = encryptor.TransformFinalBlock(toEncryptArray, 0, toEncryptArray.Length);
        return Encoding.UTF8.GetString(resultArray);
    }
}

1.6.3、編寫(xiě)API接口

/// <summary>
/// 解密接口
/// </summary>
/// <param name="ciphertextpwd">密碼密文（待解密）</param>
/// <param name="publicKey">公鑰</param>
/// <param name="privateKey">私鑰</param>
/// <returns></returns>
[HttpPost]
public IActionResult word_Encrypt(string ciphertextpwd)
{
    string resPwd = "";
    try
    {
        resPwd = AesDecrypt(ciphertextpwd);
        return Json(new { code = 200, msg = resPwd });
    }
    catch (Exception ex)
    {
        return Json(new { code = 220, msg = "AES解密時(shí)出現(xiàn)錯(cuò)誤?。。? });
    }
}

二、前端使用“JSEncrypt”，進(jìn)行非對(duì)稱RSA加密，.NET后端解密

2.1、加密解密效果圖

前端請(qǐng)求參數(shù)加密、.NET 后端解密

2.2、非對(duì)稱加密

所謂的非對(duì)稱，即加密和解密用的不是同一個(gè)秘鑰。比如用公鑰加密，就要用私鑰解密。非對(duì)稱加密的安全性是要好于對(duì)稱加密的，但是性能就比較差了。

2.3、RSA

非對(duì)稱加密算法中常用的就是 RSA 了。它是由在 MIT 工作的 3 個(gè)人于 1977 年提出，RSA 這個(gè)名字的由來(lái)便是取自他們 3 人的姓氏首字母。我們?cè)谠L問(wèn) github 等遠(yuǎn)程 git 倉(cāng)庫(kù)時(shí)，如果是使用 SSH 協(xié)議，需要生成一對(duì)公私秘鑰，就可以使用 RSA 算法。

2.4、準(zhǔn)備工作：安裝“jsencrypt”

2.4.1、使用npm進(jìn)行安裝

npm安裝命令如下：

npm install jsencrypt

2.4.2、Visual Studio中安裝

2.4.2.1、選擇“客戶端庫(kù)”

前端請(qǐng)求參數(shù)加密、.NET 后端解密

2.4.2.2、安裝下載“jsencrypt”

在“添加客戶端庫(kù)”界面：

提供程序：選擇“unpkg”；
庫(kù)：輸入“jsencrypt@”，進(jìn)行版本的選擇；
可選擇：1、包括所有庫(kù)文件；2、選擇特定文件；

確認(rèn)無(wú)誤之后，點(diǎn)擊“安裝”即可。
前端請(qǐng)求參數(shù)加密、.NET 后端解密

2.5、安裝組件“BouncyCastle”

在菜單欄找到工具 —> NuGet 包管理器 —> 管理解決方案的NuGet程序包 —> 瀏覽 —> 搜索 “BouncyCastle” —> 安裝。
前端請(qǐng)求參數(shù)加密、.NET 后端解密

2.5.1、新建幫助類

2.5.1.1、添加C# RAS生成.NET公鑰與私鑰以及.NET公鑰與私鑰轉(zhuǎn)Java公鑰私鑰類“RASKeyConversion”

AES對(duì)稱加密實(shí)戰(zhàn)——前端js加密后端python解密
高級(jí)加密標(biāo)準(zhǔn)(AES, Advanced Encryption Standard)，是一種最常見(jiàn)的對(duì)稱加密算法。其加密流程如下圖所示，發(fā)送方通過(guò)密鑰對(duì)明文加密后進(jìn)行網(wǎng)絡(luò)傳輸，接收方用同樣的密鑰將密文解密。在前后端通訊場(chǎng)景中，可利用AES算法對(duì)用戶密碼進(jìn)行加密后傳輸，防止被抓包而造成密碼泄露。
