I have a client application that communicates with a server through a web API.
The data being communicated is not personally sensitive (no passwords, credit card details, usernames, etc). It’s just challenge/respons… Continue reading Benefit of asymmetric encryption vs trivial alternatives in compromised software?
I want to detect if a file on disk was edited since last access, or restored since last deletion. Let’s assume this isn’t on a VM.
Basic scheme:
Somewhere in the file is a cryptographic hash of the file’s last access date/time. Any modifi… Continue reading Windows/NTFS: do files have any unique, immutable properties?
I’m trying to figure out a way to set a value somewhere and read it later in a completely indirect manner, to the point where someone who’s debugging the (disassembled) area of code where the value is read would have no simple way of knowi… Continue reading C++ obfuscation: indirect communication between code segments?
I’m looking into binary obfuscation for an exectuable binary written in C++. I realize preventing cracks is impossible, but making it slightly harder would be nice.
No matter how complex the actual license scheme is, I can’t think of a wa… Continue reading C++ binary obfuscation: how to get around license checks being a simple if/then branches?
