any way to hide code or data ?

[Ahmet]

Hi,

I have one application in which I cyrpto password using a keyword.
But when a user examines my binary using ildasm, he can see both my
cyrpto key and cyrpto method.

How people hide their IL code or cyrpto information in c# ?

thanks..

I think one solution is to use RSACryptoServiceProvider, use public key to
encrypt the password. The private key which can be used to decrypt the
password, however, can be stored in key container.

That's because the originally posted URL continued onto the next line:

which admittedly gives a different error for me (on the left) but it's
got the right stuff...
