I want to create a formal letter in which I have to add a separator between paragraphs, just as the ones in the picture 
Is there a way to create a this but not by typing each asterisk below the paragraph?
Here is a MWE:
\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[spanish]{babel}
\usepackage{hyperref}
\usepackage{xhfill}
\begin{document}
\typein[\secretarioacademico]{Ingrese el nombre del secretario academico.}
QUIEN SUSCRIBE, \textbf{\MakeUppercase{\secretarioacademico}}\\
SECRETARIO ACADEMICO DE LA DIVISION DE INGENIERIAS CAMPUS IRAPUATO-SALAMANCA DE LA UNIVERSIDAD DE GUANAJAUTO, \textbf{HACE CONSTAR} QUE:\xdotfill{1pt}
\vspace{2cm}
\end{document}
Thanks.
