我使用 AESManaged Class 来加密一个 zip 文件,但它不能被 winzip/7zip 解压缩。我只能在我的代码中解密后解压缩它。
下面是我用来加密和解密的代码。任何人都可以帮忙吗?
private static void EncryptFile(string input, string output, string pwd)
{
using (AesManaged aes = new AesManaged())
{
FileStream fsCrypt=null;
try
{
byte[] key = Encoding.UTF8.GetBytes(pwd);
fsCrypt = new FileStream(output, FileMode.Create);
using (CryptoStream cs = new CryptoStream(fsCrypt, aes.CreateEncryptor(key, key), CryptoStreamMode.Write))
{
using (FileStream fsIn = new FileStream(input, FileMode.Open))
{
int data;
while ((data = fsIn.ReadByte()) != -1)
{
cs.WriteByte((byte)data);
}
aes.Clear();
}
}
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
aes.Clear();
}
finally
{
if(fsCrypt!=null)
{
fsCrypt.Dispose();
}
}
}
}
private static void DecryptFile(string input, string output, string pwd)
{
using (AesManaged aes = new AesManaged())
{
FileStream fsCrypt = null;
try
{
byte[] key = Encoding.UTF8.GetBytes(pwd);
fsCrypt = new FileStream(input, FileMode.Open);
{
using (FileStream fsOut = new FileStream(output, FileMode.Create))
{
using (CryptoStream cs = new CryptoStream(fsCrypt, aes.CreateDecryptor(key, key), CryptoStreamMode.Read))
{
int data;
while ((data = cs.ReadByte()) != -1)
{
fsOut.WriteByte((byte)data);
}
aes.Clear();
}
}
}
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
aes.Clear();
}
finally
{
if (fsCrypt != null)
{
fsCrypt.Dispose();
}
}
}
}
