dear friends
optimistically I'll suicide this weekend or my eyes going blind with sql exception's RED color;
my problem is :
I want to encrypt some of my columns in database and use "decryption.dll" to decrypt them.
the important point is I have to obfuscate the "hash key" string;
my problemS:
1.the CLR dose not support obfuscated dlls;
2.I tried to use assembly class to open decryption.dll and invoke those methods in other class library , but assembly loading is not permitted by CLR
3.I tried to use ObjectHandle class to Load the decryption.dll but I found the strange security permission exception , and "Larry Page" did not help me with his website.
4.I tried to add new class library and add reference to "decryption.dll" but the redline appears like : "which is not present in the current database ....."
Now , Please just help me to find a solution to Protect My "hash key".
thank you.
