The major issue I found is that you wrote your own crypto system without developing a security model and without explaining why well-known and well-tested crypto methods aren&#x27;t appropriate.<p>I don&#x27;t think that can be so easily fixed.<p>Again, unless you are an expert, do not write your own crypto system and try to encourage others to use it. Even for experts it&#x27;s hard work.<p>Just because you or random strangers on the internet can&#x27;t break it in 5 minutes of side project, doesn&#x27;t mean it&#x27;s not breakable.
