Yeah, there’s no telling how secure it is. Works, yes. Easily circumventable, maybe, maybe not. There’s a lot of math involved and I’m by no means an expert at any of it or guaranteed to have implemented everything correctly. For my personal purposes it’s 100% secure unless you know wtf you are looking at (much like a one-time-pad). Once the code and algorithms are published, it’s only secure until someone breaks it.
