hi all

i am using des symmetric crypto.
i need to encrypt my app packets.

i use XmlSerializer,
to serialize my packets into a memory stream.
i then extract the byte array.

i encrypt this array,
and all works well.


however, when i use a BinaryFormatter,
instead of the XmlSerializer,
the Deserialize fails!


what must i do in order to encrypt while using BinaryFormatter?

Just use the crypto stream API. Have a look at the docs for CrypoStream
for an example.

See the example you find in the CryptoStream docs.

1) Use a different stream instead of FileStream
2) The example in "about CryptoStream" doesn't use strings - it's
encrypting one file and writing it out as another

Try following the example through, line by line, and you'll see how to
use CryptoStream for your case.
