in reply to xkcd-style password generation

With a little adaption: 
perl -le '@w=grep{length()>5&&length()<8&&/^[a-z]+$/}<>;chomp@w;print 
+join" ",map{$w[rand@w]}1..4'</usr/share/dict/words

[download]
Some samples: 
octyl forrad ruble smoked
unlit stamp finish stumpy
baring pattu helium place
tiptop sundri alumni anilla
dodge blout spurl fasher
lownly setal untar nuchal

[download]
There are 23560 entries in my /usr/share/dict/words that match, giving 308106701416960000 different potential pass phrases. If an attacker can test 1 billion pass phrases per second, it takes almost 10 years to check the entire key space.

I consider that secure enough for my Perlmonks password.

    Hahaaaa... ++ just for saying "secure" and "Perlmonks password" in the same sentence with a straight face. :-P :-) Plaintext passwords? Hahaha... thanks for that :-)

      Plaintext passwords?

      Someone remind me again; why is it so hard to change that?

      With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
      Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

      In the absence of evidence, opinion is indistinguishable from prejudice.

      The start of some sanity?
