  • .NET实现AES加密解密

    AES加密有五种密码模式。.NET 内置的AES加密对象仅实现了两种(CBC、ECB),如果要实现OFB、CFB、CTR加密,仅仅只靠.NET内置的AES加密对象就无法实现了。如果想要实现的话,可以依靠一款强大的.NET 加密库:BouncyCastle.dll (nuget 上可找到 .NET Core版本:BouncyCastle.NetCore)。

    今天作者向大家推荐的是一款依赖BouncyCastle.NetCore.dll实现加密的.NET 组件库:ZHI.ZSystem。

    相对于.NET内置AES加密对象,它有以下优势:

      1.可以实现OFB、CFB、CTR、CTS加密

      2.静态函数调用,操作简单方便

    相对于BouncyCastle加密库,它有以下优势:

      1.底层依赖BouncyCastle加密库,bug少

      2.调用函数方式简单,参数清晰明了,注释齐全

    接下来我们用代码来证明吧!

    1.nuget 搜索 ZHI.ZSystem并安装(目标框架是.NET Standard 2.0,所以.NET Core 和 .NET Framework都可以下载并使用)

     

    2.调用AES加密/解密方法。(真的超级简单!)

    3.得到结果。(下面我贴一下自己的加密结果)

    介绍完了用法,担心小伙伴们还是不太会用,所以把代码贴出来!

    /// <summary>
    /// 单元测试 记得引用ZHI.ZSystem库
    /// </summary>
    [Test]
    public void Test()
    {
        //AES KEY 128 BIT
        var aes_key = "dyoo9IaP1NbuMOwk";
        //AES IV 16 BYTE
        var aes_iv = "kT0mtWAHg1lEympP";
        // plaintext
        var plaintext = "嘿嘿嘿 $&*!";
    
        //BASE64 输出
        var ciphertext_base_64_output = EncryptHelper.AESEncryptToBase64(plaintext, aes_key, aes_iv, AesCipherMode.CBC, AesPaddingMode.PKCS7Padding);
        //Hex 输出(十六进制输出)
        var ciphertext_hex_output = EncryptHelper.AESEncryptToHex(plaintext, aes_key, aes_iv, AesCipherMode.CBC, AesPaddingMode.PKCS7Padding);
        //AES 解密 BASE64
        var base_64_decrypt = EncryptHelper.AESDecryptFromBase64(ciphertext_base_64_output, aes_key, aes_iv, AesCipherMode.CBC, AesPaddingMode.PKCS7Padding);
        //AES 解密 Hex
        var hex_decrypt = EncryptHelper.AESDecryptFromHex(ciphertext_hex_output, aes_key, aes_iv, AesCipherMode.CBC, AesPaddingMode.PKCS7Padding);
    
        Console.WriteLine("CBC密码模式");
        Console.WriteLine("     加密结果base64输出:{0}", ciphertext_base_64_output);
        Console.WriteLine("     加密结果hex输出:{0}", ciphertext_hex_output);
        Console.WriteLine("     解密base64:{0}", base_64_decrypt);
        Console.WriteLine("     解密hex:{0}", hex_decrypt);
        Console.WriteLine();
        //BASE64 输出
        ciphertext_base_64_output = EncryptHelper.AESEncryptToBase64(plaintext, aes_key, aes_iv, AesCipherMode.CFB, AesPaddingMode.PKCS7Padding);
        //Hex 输出(十六进制输出)
        ciphertext_hex_output = EncryptHelper.AESEncryptToHex(plaintext, aes_key, aes_iv, AesCipherMode.CFB, AesPaddingMode.PKCS7Padding);
        //AES 解密 BASE64
        base_64_decrypt = EncryptHelper.AESDecryptFromBase64(ciphertext_base_64_output, aes_key, aes_iv, AesCipherMode.CFB, AesPaddingMode.PKCS7Padding);
        //AES 解密 Hex
        hex_decrypt = EncryptHelper.AESDecryptFromHex(ciphertext_hex_output, aes_key, aes_iv, AesCipherMode.CFB, AesPaddingMode.PKCS7Padding);
        Console.WriteLine("CFB密码模式");
        Console.WriteLine("     加密结果base64输出:{0}", ciphertext_base_64_output);
        Console.WriteLine("     加密结果hex输出:{0}", ciphertext_hex_output);
        Console.WriteLine("     解密base64:{0}", base_64_decrypt);
        Console.WriteLine("     解密hex:{0}", hex_decrypt);
        Console.WriteLine();
    }

    看完有没有觉得特别简单呢!
