What do you mean by bin?
There are many possible things you could mean, and they
have very different answers. For instance you could be
looking for an encryption module, of which there are
several on CPAN. Or you might be looking for pack and
unpack. If you are on Windows try this:
perl -ne "print unpack("B*", $_)" input_file > output_file
(Use single quotes on Unix.)
You can reverse it with:
perl -ne "print pack("B*", $_)" input_file > output_file
See pack, unpack, and perlrun for more.

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).
