如果我有 IV、加密数据和结果值，我能找到 Triple DES 加密算法中的密钥吗？
这并不意味着任何类型的黑客攻击，我只是尝试在 .NET 中使用 Triple DES 加密技术。我身上有一些测试数据。我必须用给定的数据得到结果。我也有结果了。但价值永远不会匹配。我确信代码没问题（将在下面给出）。所以我认为唯一的可能性可能是密钥错误，所以让我们找到密钥并看看是否匹配。下面是我的代码：
byte[] key = StringToByteArray("5b70649d4ae0bf2af891c167514aa7515b70649d4ae0bf2a");
byte[] iv = new byte[] { 0, 0, 0, 0, 0, 0, 0, 0 };
byte[] bytes = Encoding.ASCII.GetBytes("95e4d77c6d6c6c993333303533303833");
TripleDESCryptoServiceProvider tripleDes = new TripleDESCryptoServiceProvider();
tripleDes.Mode = CipherMode.CBC;
//tripleDes.Padding = PaddingMode.None;
tripleDes.Key = key;
tripleDes.IV = iv;
MemoryStream ms = new MemoryStream();
ICryptoTransform encryptor = tripleDes.CreateEncryptor();
CryptoStream cs = new CryptoStream(ms, encryptor, CryptoStreamMode.Write);
cs.Write(bytes, 0, bytes.Length);
cs.FlushFinalBlock();
byte[] cipher = ms.ToArray();
string finalValue = ByteToString(cipher, 16); //ByteToString method will convert byte array to string.
最终结果是1B529558534F43D15556AD65C7E396D5674EE8A09E0A29A84389020EF820AC51B7D5E1B33BDA18A2。 由于我只需要 16 个字节，因此我仅将前 16 个字节转换为十六进制 1B529558534F43D15556AD65C7E396D5。
但预期结果是76db821f5c7af12dc8d70a6a79cfcb77 如果我能找到密钥，我可能知道密钥中也需要进行某种处理。
感谢您的帮助！
This is not meant for any kind of hacking, I am just trying my hands on Triple DES encryption technique in .NET. I have some test data with me. I have to get the result with the given data. I do also have the result. But the value never matches. I am sure the code is fine (will give that below). So I thought the only possibility could be the key is wrong and so lets find the key and see if that matches. Below is my code:
byte[] key = StringToByteArray("5b70649d4ae0bf2af891c167514aa7515b70649d4ae0bf2a");
byte[] iv = new byte[] { 0, 0, 0, 0, 0, 0, 0, 0 };
byte[] bytes = Encoding.ASCII.GetBytes("95e4d77c6d6c6c993333303533303833");
TripleDESCryptoServiceProvider tripleDes = new TripleDESCryptoServiceProvider();
tripleDes.Mode = CipherMode.CBC;
//tripleDes.Padding = PaddingMode.None;
tripleDes.Key = key;
tripleDes.IV = iv;
MemoryStream ms = new MemoryStream();
ICryptoTransform encryptor = tripleDes.CreateEncryptor();
CryptoStream cs = new CryptoStream(ms, encryptor, CryptoStreamMode.Write);
cs.Write(bytes, 0, bytes.Length);
cs.FlushFinalBlock();
byte[] cipher = ms.ToArray();
string finalValue = ByteToString(cipher, 16); //ByteToString method will convert byte array to string.
The final result is 1B529558534F43D15556AD65C7E396D5674EE8A09E0A29A84389020EF820AC51B7D5E1B33BDA18A2.
Since I need only 16 bytes I have converted only first 16 bytes to hex 1B529558534F43D15556AD65C7E396D5.
But the expected result is 76db821f5c7af12dc8d70a6a79cfcb77
If I can find the key, I may know that there needs to be some kind of processing required in the key as well.
Thanks for the help!

虽然这当然是可能的，但我不认为 TripleDESCryptoServiceProvider 类被设计为“反向”工作，以便在您拥有密码、IV 和未加密数据时为您提供密钥。为什么应该这样？
While its certainly possible, I don't think the TripleDESCryptoServiceProvider class is designed to work in "reverse" to give you a key when you have the cypher, IV and the unencrypted data. Why should it?
