I would like to know how I can know which is the safest compilation line, that is:
Having several compilation lines in, for example, GCC, how do I know which one is more secure? Hardening would be a good solution? What do you recommend?
Do… Continue reading How do I compare the safety of a compiled program with optimization flag?

does a mere recompilation make a program more secure against attacks?
You have the source code of a program, compile it two times with the same options. One of the binaries yo… Continue reading Does recompiling a binary from source code make it more secure/obscure?
‘Reproducible builds’ ensure that a published app matches the published open source code. This answer gives some great information on it.
But numerous sources1,2 indicate reproducible builds are very difficult (or even impossible) to imple… Continue reading Are reproducible builds practically possible on major app stores?
How to compile or cross-compile StrongSwan (VPN) for the Android Kernel. I’m not talking about the .APK but the c++ binaries from the source code.
I read the official documentation which talks about compiling StrongSwan for compiling stron… Continue reading StrongSwan compiled for Android Kernel root [migrated]
It is a common problem these days. You have a piece of code in C or C++. Maybe it is older code. Or maybe you prefer prototyping your ideas using C. But, inevitably, someone now wants your code to run in a Web browser. The options for making this happen …read more
It sounds like the start of a joke, but what’s the difference between taking Cornell’s CS6120 online and in-person? The instructor, [Adrian Samspon] notes that the real class has deadlines, an end-of-semester project, and a discussion board that is only open to real-life students. He also notes that you only …read more
In Cryptography Engineering Ferguson, Schneier and Kohno put a big emphasis on quality of code in order to prevent it from leaking information and from being vulnerable to memory corruption exploits.
Re-implementing cryptography, especiall… Continue reading Compiler-induced information leaks/side-channels in cryptography implementations
Numerous websites allow us to build and execute C code from web browsers (repl.it, onlinegdb.com, ideone.com…). For my own application (education purposes) I would like to do the same on my web backend.
My current solution is to use an A… Continue reading Build and execute code on a sandboxed environment?
I was wondering when people compile malware and use the compiled files for engagements or nefarious purposes, what evidence do they leave behind in the compiled Windows executables? I have heard that the OS usernames of the compilers can b… Continue reading What evidence does a compiled file leave behind?
