C++(crypto++）和C#加密匹配

为了客户端和服务器之间的安全通信，我想对来自客户端和服务器的数据进行加密和解密，但我无法获得相同的结果，从客户端到服务器的数据没有解密，而且当对来自服务器的相同数据进行加密时，我会从客户端的加密中获得不同的结果。

客户端是使用Crypto++用C++编写的。代码：

string data = "teststring,teststring,teststring";
string encryptedData = client.encrypt(userData, "01234567891234560123456789123456", "0123456789123456");

string Client::encrypt(const string& str_in, const string& key, const string& iv)
{
try {
string str_out;

AES::Encryption aesEncryption((byte*)key.c_str(), key.length());
CBC_Mode_ExternalCipher::Encryption encryption(aesEncryption, (byte*)iv.c_str());

StringSource encryptor(str_in, true,
new StreamTransformationFilter(encryption,
new Base64Encoder(
new StringSink(str_out),
false
)
)
);
return str_out;
}
catch (exception e) {
return "null";
}
}
string Client::decrypt(const string& str_in, const string& key, const string& iv)
{
try {
string str_out;
CBC_Mode<AES>::Decryption decryption((byte*)key.c_str(), key.length(), (byte*)iv.c_str());

StringSource decryptor(str_in, true,
new Base64Decoder(
new StreamTransformationFilter(decryption,
new StringSink(str_out)
)
)
);

return str_out;
}
catch (exception e) {
return "null";
}
}

给出以下输出：

data: "teststring,teststring,teststring"
encryptedData: "STpuD/dRgYard+Yqpdd5KOYET7607i7ZRUoKm5eshHzR3ErafaxgZ2+T1tSp0lWJ"

服务器端的代码是用C#(ASP.NET Core 3.1(编写的：

public static string Encrypt(string input)
{
byte[] clearBytes = Encoding.Default.GetBytes(input);

using (Aes encryptor = Aes.Create("AES"))
{
// encryptor.BlockSize = 32;
encryptor.Padding = PaddingMode.Zeros;
encryptor.KeySize = 128;
encryptor.Mode = CipherMode.CBC;
encryptor.Key = Encoding.Default.GetBytes("01286567891233460123456789123456");
encryptor.IV = Encoding.Default.GetBytes("0123456789123456");
using (MemoryStream ms = new MemoryStream())
{
using (CryptoStream cs = new CryptoStream(ms, encryptor.CreateEncryptor(), CryptoStreamMode.Write))
{
cs.Write(clearBytes, 0, clearBytes.Length);
cs.Close();
}
byte[] bt = ms.ToArray();
input = Convert.ToBase64String(bt);
}
}
return input;
}

public static string Decrypt(string input)
{
byte[] clearBytes = Encoding.ASCII.GetBytes(input);

using (Aes decryptor = Aes.Create("AES"))
{
//decryptor.BlockSize = 32;
decryptor.Padding = PaddingMode.Zeros;
decryptor.KeySize = 128;
decryptor.Mode = CipherMode.CBC;
decryptor.Key = Encoding.ASCII.GetBytes("01234567891234560123456789123456");
decryptor.IV = Encoding.ASCII.GetBytes("0123456789123456");
using (MemoryStream ms = new MemoryStream())
{
using (CryptoStream cs = new CryptoStream(ms, decryptor.CreateDecryptor(), CryptoStreamMode.Write))
{
cs.Write(clearBytes, 0, clearBytes.Length);
cs.Close();
}
byte[] bt = ms.ToArray();
input = Encoding.ASCII.GetString(bt);
}
}
return input;
}

输出：

data: "teststring,teststring,teststring"
encryptedData: "tIDlWnnzOQWh5HIvRDJya6z7jOglkIlYrICeYW9RoEM="

我无法解密来自客户端和服务器的数据。请帮帮我。
