Question

我想要做的是解密文件并将Hex保存到数组中。我现在遇到的问题是当我用十六进制值的十进制表示提取它时，我无法将其转换回来

代码：

    int bits;
    DecryptFile
    (Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData) + 
     @"\Akd3\CFS.exe");
    }
    private void DecryptFile(string input)
    {
        string password = @"treeessss";
        byte[] Key = Encoding.ASCII.GetBytes(password);

        RijndaelManaged AES = new RijndaelManaged();

        FileStream FCrypted = new FileStream(input, FileMode.Open);
CryptoStream cs = new CryptoStream(FCrypted, 
AES.CreateDecryptor(Key, Key), CryptoStreamMode.Read);
        int data;
        while ((data = cs.ReadByte()) != -1)
        if((data = cs.ReadByte()) != -1)
        {
            bits = bits + data;
        }

关于如何提取字节或转换十进制表示的任何想法都会非常有用，谢谢

您可以使用以下代码从byte[]获取CryptoStream：

byte[] result;
using (MemoryStream ms = new MemoryStream())
{
    using (CryptoStream cs = new CryptoStream(ms, transform, CryptoStreamMode.Write))
    {
        cs.Write(inputData, 0, inputData.Length);
    }
    result = ms.ToArray();
}

显然cs.Write...行可以替换为调用另一个流来复制到cs

Cryptostrem到byte []数组
