Text environment with vertical header and border

Question

I have no experience with creating latex environments, so I hope that someone would be so kind helping me trying to create a new text environment with a border and a vertical header to the right of the text area.

I've tried to depict it using my MS Paint skills:

Is there anyone who can help me create such an environment or give me some hints on how to do it? Any help will be much appreciated.

As I wrote in the comment I suggest the package mdframed. I am sure the packages framed or tcolorbox are also able to do this.

All listed options can be found in the documentation. I also recommend the example of the question mdframed-Put something on the start of one vertical left rule where I explain most of the following code.

\documentclass{article}
\usepackage[framemethod=tikz]{mdframed}
\usetikzlibrary{calc}%need for tikz let operation
\usepackage{kantlipsum}%filling text

\newmdenv[%
 skipabove=\topskip,%
 skipbelow=\topskip,%
 rightmargin=.5cm,%
 leftmargin=2cm, %
 middlelinewidth=2pt,%
 middlelinecolor=blue!70,%
 firstextra={\path[overlay]  let \p1=(P), \p2=(O) in ($(\x2,0)+1*(0,\y1)$) 
                           node[rotate=90,anchor=east,yshift=2em,font=\bfseries\large] {Short Header};},%
 singleextra={\path[overlay] let \p1=(P), \p2=(O) in ($(\x2,0)+1*(0,\y1)$) 
                           node[rotate=90,anchor=east,yshift=2em,font=\bfseries\large] {Short Header};},%
]{myframe}
