For those who wish to satisfy their misplaced curiousity or boredom, what Ste+ve meant was:
## replace modifyKeys with below code
sub modifyKeys {
my $self = shift;
my $S_KEY = "";
my ($i, $x);
for my $x (0..length($self->{R_KEY})-1) {
$i = ord(substr($self->{R_KEY}, $x, 1)) - 32;
$S_KEY .= chr(($i ^ $self->{RSORT}[$i] ^ $self->{ATT}) + 32)
}
return $S_KEY;
}
## fix up the following line in sub cipher() ##
my $i = (length ($self->{xString}) % $keylen); # DATA DEPENDENT SHIF

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).
