Those will save his time and worries about security by the user community. While I have a PhD in astronomy and had several years of advanced math as an undergraduate, I do not have the mathematical qualifications to build a new encryption algorithm. Folks who do that kind of work need to have a very deep understanding of number theory and related subjects. 'Nuff said. Bruce B.
