where to store the strings in main app

[PillKilla]

Hi guys,

I need your help. I want to create the matched strings in vb.net and set them as private, so no one could read them when using ollydby.


Here's the code:

Dim a As string = "ˆ"
Dim b As string = "%"
Dim c As string = "ÿ"
Dim d As string = "o"


if a & b & c & d then
'find the matched strings and set them together...'
end if

I want to know how to set the matched strings by finding them in main app, then get the matched strings and make the words join in together. For e.g: the strings of "ˆ" stands for h, "%" stands for e, "ÿ" stands for l and "o". So the words for altogether would be "hello". I also curious where is the best place to store the matched strings of "hello" somewhere in the main app without anyone could tracking them??


Any info would be much appreciate.

Thanks in advance.

you could use encryption or a binary file that holds the codes for each letter of the alphabet

Thanks for your help, so where should I store the encrypted key in the main app and is it safe to store the encrypted strings in app.config or they can still be decrypt?


Thanks,

No, I am asked the one where to store the private key secure in the main app??

[Jenner]

Depends on how secure you want it. There is no totally secure way to store a static symmetrical key. They can all be broken. You could store it encrypted, but then you'd need to store the key that encrypted that... You can store it broken into pieces or symbolons, but the program has to re-arrange them together at some point and that's when it can be obtained.

The only really secure way to do it is have the user enter the key or a portion of the key themselves; in the form of a password.
