 Hide passwords from code !!

Hello,

Take a look at this: http://www.*-*-*.com/
decompiler of C#, VB.NET, .... Is amazing!!.

Well, after this, we have found a big problem. We have to include several
passwords to use in our program. At this time, we have it as private members
of a class, but after seeing this, we don't know how to hide / protect this
passwords, any idea??

greetings,
ral

P.D. I have saw some 'obfuscators' of IL code, but we'd like to find a
easier solution

Hi,
Just try thinstall, ( www.lesser-software.com/thinstall.htm ).
Thinstall contains a virtual file-system.
From the outside it will appear as one exe.
Thinstall is a great protector, "securing" your .NET code.
In case of an exe no .NET Assemblies can be seen from outside.

There's no way you can stop someone with a de{*filter*} from getting any
password that you store in a program.  Even if it's an algorithmic
password (like the program asking the user one of many questions, etc,
or to compute a formula based on the day of the week, etc.) someone
that has access to a debu
598
gger and some determination will be able to extract the password from
the binary code.  No amount of obfuscation can prevent that -- it can
only make it harder.

I'd suggest reading "Writing Secure Code". It has a section on storing
secrets, IIRC.
