Secure log file

[jacky Wang]

I'm using CVI8.1. I have a CVI program which logs some very secret data from server to local machine. So I'm looking for a way to secure it. Is there any good idea on it?

Thanks!

Before thinking to an actual solution you must decide how to handle this problem, since I can figure at least three different approaches to it:

1. Leave data on the server and read only the portion needed moment by moment never saving anything on local disk
2. Rely entirely on security and authorization functions the OS can grant you
3. Write a local encrypted copy of your data on local disk

Regarding option #3 and if you are in Windows environment, you may find useful CryptEncryptMessage and CryptDecryptMessage SDK functions, together with a small tutorial and some example code that can be find in SDK.
