I want to make a document that looks like an old top secret file written on a typewriter. The problem is that when I want to use a `center` environment, the alignment of the characters is off. Is there a way to make sure that the boxes of all the characters are aligned while still making use of the `center` environment?

MWE

\begin{center}
Top Secret Document
\end{center}
This is a top secret document containing secret information about a secret thing which has remained secret for many years. This is a top secret document containing secret information about a secret thing which has remained secret for many years.
