Português: Este conjunto de arquivos apresenta a teoria helicoidal Fn desenvolvida por Bruno Becker, aplicada à geração de chaves criptográficas em curvas elípticas (ECC). A fórmula F(n)=sin⁡2(2πφx)F(n)=sin2(2πφx), onde x=n−r42x=42n−r e φφ é a razão áurea, organiza os números primos em uma estrutura harmônica helicoidal.
