On at least one wifi network I've tried that required an ascii WEP key, the s: prefix option for dsl's iwconfig - signifying an ascii key - just would not work for me. After I used the hex equivalent instead, it connected immediately.
So I thought a converter from asci keys to hex keys might be handy.
Anyway it made a compact little homework exercise for myself, so thought I might share.
In bash:
| Code Sample | #!/bin/bash
#
# asci2hexkey.sh
# Coverts ascii key to hex on the fly
ASCIKEY=""
echo "Type in ascii wifi key:"
while read -s -n 1 ASCHAR; do
[ "$ASCHAR" = "" ] && break
printf "%X" $(printf "%d" \'"$ASCHAR"\')
ASCIKEY=${ASCIKEY}${ASCHAR}
done
echo " = ascii key \"$ASCIKEY\"" |
Also did it differently using perl, after googling for the gist:
| Code Sample | #!/usr/bin/perl
#
# asci2hexkey.pl
# Takes asci key as command line argument & prints hex
#
use strict;
use warnings;
my $asciichars = shift;
chomp $asciichars;
my $hexchars = '';
foreach my $c (split(//,$asciichars)) {
$hexchars .= sprintf "%x", ord($c);
}
print "$hexchars\n"; |
User should insert hyphens every four chars into the resulting hex key when using with iwconfig.
