[Tex/LaTex] Vertical line in the middle of the page

Question

How can I get a vertical line in the middle of the page ? and I want also to write same text in the right and the left of the vertical bar (like this example) :

I tried \rule but i don't know how to write same text in the right or left.

Answer 1

Such a rule is built in to the output routine in the format:

\documentclass[twocolumn]{article}
\setlength\columnseprule{1pt}
\raggedright
\begin{document}

\begin{flushright}
\vspace*{\fill}

\textbf{Informations}

\vspace*{\fill}
\end{flushright}

\pagebreak

\textbf{Author:}

Name
\bigskip

\textbf{Subject:}
Title
\end{document}
