arithmetic operator obfuscation (source)

[DefCon42]

https://github.com/DefCon42/op-mutation

 

decided to release the source because it's a neat example of a practical application of linear algebra

yes, i know the code does not look great and there's blatant violations of like every standard ever

no, i won't change that :^)

 

note: only works with relatively simple operations. add, sub, not, etc will work but higher order operators like multiplication and exponentiation will not

What are missing are: compiled exes, examples of usage (how to use it),
question: why it is using GMP math lib for simple instructions?
