This may have seemed like a great idea in 2013, but the repeated "set/clear bits", a.k.a. clamping phases at each level of the hierarchy slowly subtract key strength.
Don't use this as described. Check out Ristretto.
Semi-private keys are an expansion of the traditional idea
It is possible to compile Go programs for a different OS, even though go build says otherwise.
You'll need:

tl;dr You should watch this.
It's interesting to me that a significant number of talks in this year's Strange Loop conference referenced a 1966 paper by Peter Landin called (somewhat tongue in cheek) "The Next 700 Programming Languages". In this paper, Landin describes a programming language which he says in a footnote might be aptly called "Church without the lambda" - but which in the paper is called "If You See What I Mean" (ISWIM).
Alvaro's talk delved deeply into the question of "What is the semantics or meaning of a program?" Alvaro's thesis is that the meaning of a program is to produce desired outcomes from a computing system but that current languages focus on
