ngPost VS llvm-string-obfuscator

ngpost is very beginner friendly, try using that instead

I tested some time ago and the one I liked the most is ngPost (https://github.com/mbruel/ngPost). It handels RARing, par2, password protection and obfuscation by itself and spits out a ready .nzb file. I needed a tool that can be used via command line, which worked fine, but i just saw that it also has a GUI if you need that

Why are you trying to compile it from source ?

I assume standard obfuscation only consists of renaming the files and then posting normally while article obfuscation is modifying the subject like in the nyuu issue above. If someone is familiar with ngpost, are there 3 levels of obfuscation available here - article, filename and archive name? I can’t imagine much use for filename obfuscation if the other two are used, is everything else unnecessary with article obfuscation? The ngpost author also seems to be against obfuscation in general

ngPost may be a good program to start with as it also has a GUI (graphical user interface): https://github.com/mbruel/ngPost

Last commit was on 2021-05-16. I personally wouldn't consider it abandoned at this stage. (besides, the Usenet upload scene is full of people using abandoned software, so I'm not even sure abandonment means much anyway)

Actually, both are incorrect, and I explain why that's a bad idea. The behaviour may have been true in the past, but isn't today (and as mentioned, writing temporary files sucks for performance).

The Nyuu wiki has a good comparison. If you're familiar with a command line Nyuu itself is a good choice, if not choose one of the programs with a GUI like ngPost or JBinUp (doesn't have a site anymore and isn't actively maintained).

There's at least one plugin for LLVM to obfuscate strings from binaries [1], and for Android there is DexGuard [2]. The general idea is to make life as difficult as possible for reverse engineers, crackers and whomever else - hardcoded stuff just showing up in "cat .binfile | strings" is about the first thing I do when investigating some random stuff, and there's tools like binwalk that can automatically do stuff like extracting PEM certificates and other easily identifiable content.

For my use case, I need to create a llvm plugin which does some basic obfuscation to deter reversing of my application. I'm well aware obfuscation will not fully protect my application, but would like to implement it because one, the concept is interesting to me, and two, it will serve as a barrier to entry and might discourage some lazy bad actors. As an example, I have been referencing this project https://github.com/tsarpaul/llvm-string-obfuscator/blob/master/StringObfuscator/StringObfuscator.cpp , but would like to keep my code base totally in rust. I've searched around crates.io and can't find any library exposing bindings to the plugin pass api of llvm. Is there a crate already available to facilitate creating llvm passes in rust, or does anyone have any resources to suggest which could get me on the right path? I've created basic sys bindings for a c++ library (https://github.com/0xFounders/detour-sys), but am not an expert and was hoping there was already an established way to access the llvm pass api in rust.
