I used this ruby one-liner
ruby -e "puts File.readlines('List of English Words.txt').find_all{|word| word =~ /^[abcdef]+\n$/i}"
and a file containing a large list of English words (and acronyms) to make the following list of English words that only use “hex letters” or letters a through f.

Perhaps you can use these to make your WEP wifi password easier to rattle off to your guests.
“BA” is a word?
“ABC” is a word?
“AFB” is a word?
Ba and ABC make sense. At least they’re reasonable “words” to have in a “large list of english words”. That’s where these “words” come from. The dictionary is perhaps too liberal. I’m not sure why afb is in there. Perhaps it’s an acronym, but obviously not a very well known one.
I truly do agree with all of the ideas you’ve presented in your own article. They are very authentic and will surely work. Still, the posts are very short for newbies. Could you make sure you extend them a bit from the next time? Many thanks for the write-up.
