How to use: drag and drop files into the executable icon. You will be asked for a password. The program will then create encrypted files with the ".gpg" extension (it will not delete the original files for you).
If you drop files with the ".gpg" extension, the files will be un-encrypted back.
Installation: use "PAR" (or Perl2EXE/PerlApp) to make an executable file, and copy it to the pen drive. You will need to copy the "gpg" executable to the same directory.
I've tested it with perlapp, in Windows XP and NT.

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).
