با سلام
مطمئنید خوب گشتید؟
قبلاً با این کد کار میکردم که از code project گرفتم
private void EncryptFile(string inputFile, string outputFile)
{
try
{
string password = @"myKey123"; // Your Key Here
UnicodeEncoding UE = new UnicodeEncoding();
byte[] key = UE.GetBytes(password);
string cryptFile = outputFile;
FileStream fsCrypt = new FileStream(cryptFile, FileMode.Create);
RijndaelManaged RMCrypto = new RijndaelManaged();
CryptoStream cs = new CryptoStream(fsCrypt,
RMCrypto.CreateEncryptor(key, key),
CryptoStreamMode.Write);
FileStream fsIn = new FileStream(inputFile, FileMode.Open);
int data;
while ((data = fsIn.ReadByte()) != -1)
cs.WriteByte((byte)data);
fsIn.Close();
cs.Close();
fsCrypt.Close();
}
catch
{
MessageBox.Show("Encryption failed!", "Error");
}
}
private void DecryptFile(string inputFile, string outputFile)
{
{
string password = @"myKey123"; // Your Key Here
UnicodeEncoding UE = new UnicodeEncoding();
byte[] key = UE.GetBytes(password);
FileStream fsCrypt = new FileStream(inputFile, FileMode.Open);
RijndaelManaged RMCrypto = new RijndaelManaged();
CryptoStream cs = new CryptoStream(fsCrypt,
RMCrypto.CreateDecryptor(key, key),
CryptoStreamMode.Read);
FileStream fsOut = new FileStream(outputFile, FileMode.Create);
int data;
while ((data = cs.ReadByte()) != -1)
fsOut.WriteByte((byte)data);
fsOut.Close();
cs.Close();
fsCrypt.Close();
}
}
استفاده :
private void btnEncrypt1_Click(object sender, EventArgs e)
{
EncryptFile(@"D:\(1) Pad.avi", @"C:\Test\Encrypt.avi");
}
private void btnDecrypt_Click(object sender, EventArgs e)
{
DecryptFile(@"C:\Test\Encrypt.avi", @"C:\Test\Decrypt.avi");
}
