image encryption, need help!!

Mar 31 2006 11:24 AM
Hello, I am having a hard time encrypting a tiff image.  If anyone can share any insight into this matter, i would appreciate it.

Here is my encrypt method...

private byte[] Encrypt(byte[] bytes)
{
   key =
new byte[8];
   iv =
new byte[8];
  
for (int x = 0; x < 8; x++)
   {
      key[x] = Convert.ToByte(textBox3.Text[x]);
      iv[x] = Convert.ToByte(textBox4.Text[x]);
   }
  
   DESCryptoServiceProvider cryptProvider =
new DESCryptoServiceProvider();
   ICryptoTransform transform = cryptProvider.CreateEncryptor(key, iv);
   MemoryStream ms =
new MemoryStream();
   CryptoStream cs =
new CryptoStream(ms, transform, CryptoStreamMode.Write);
   cs.Write(bytes, 0, bytes.Length);
   cs.FlushFinalBlock();
   ms.Flush();
  
return (ms.GetBuffer());
}
