Hmmm...good point. Don't get me wrong, I'm not saying this is strong crypto by any stretch of the imagination. It does, however, have more than a one-to-one substitution for the commonly used characters. For example, if "r" comes up as the first of the two characters it grabs, it chooses from 10 different names. For less frequently used letters, say "x" for example, it is a one-to-one substitution. At first I was thinking the Acme:: name space, but it does actually provide a somewhat higher degree of security than Crypt::Rot13, for example. Since Rot13 is a true one-to-one subsitution cipher, I suppose a better argument could be made for moving Rot13 to the Acme:: namespace than for keeping Playwright under the Crypt:: namespace, though.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
