Javassist VS obfuscator

ClassPool comes from Javaassist library. It gives convenient API to retrieve the line number of Java method.

This problem can be resolved by https://github.com/jboss-javassist/javassist/blob/master/src/main/javassist/util/proxy/DefineClassHelper.java perfectly, I will use some of its code to fix this problem on 0.0.1

Other higher-level abstractions like Javassist: are all based on ASM, but have a nicer and easier-to-understand APIs to deal with.

In the following snippet, the transformer uses Javassist:

Seeing as there are no WebAssembly obfuscators, I decided to try to build Emscripten with an LLVM-based obfuscator. Specifically, I built it using Hikari, which is based on the obfuscator-llvm project. This was built for research purposes and may not be practical in real-world scenarios, but I thought I'd share it here anyways!

Love this topic. I remember Everquest used to checksum areas of memory that were commonly modified from cheats. World of Warcraft used to (possibly still does, it has been forever since I looked at this) inject anti cheat code at runtime.

Obfuscation and deobfuscation is also super interesting. I think overall reverse engineering and figuring out how things work is one of the most interesting things in computer science.

obsfucator-llvm -- compiler suite that produces obsfucated binaries.

5- Ah, no. https://github.com/obfuscator-llvm/obfuscator/wiki but I see why you said that, I didn't mean to use shitty app to make your code harder to read, I apologise I meant changing the actual binary, use different opcodes mutate the code, etc.. like llvm obfuscator not this shit. but if I were you I would say the same since I didn't clarify this point.

the obfuscator-llvm project is a nice place to look at when introducing yourself to some fundamental obfuscation techniques like control-flow flattening and opaque predicates, which operate on top of assembly instructions and what are called basic blocks.
