Hey all

I seen the following link on whilst trying to find out more about encrypting:
http://www.codeproject.com/KB/vb/VB_NET_TripleDES.aspx?fid=70758&fr=26#xx0xx

Anyway, my question is how can you stop somebody creating a dummy DLL with the same naming conventions (assuming of course they havent use obfescution(sp?) to hide things), and decrypting the info with your own libraries?

Does the following section of code (when creating the keys) really help limit that?  And also I'm assuming that you can put any values in for the key and iv?  Or am I wrong?
byte[] key = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 

              13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24};

byte[] iv = {8, 7, 6, 5, 4, 3, 2, 1};

1) sign your dll ... its a super pain to get around this (i.e. hacking the CLR painful)
2) use public key encryption for any data you want to keep from changing ... they will be able to view the data but not change it.

How do you go about doing 1 and 2?  Would that solve my problem of having the byte key in every form?
