SYNOPSIS

DESCRIPTION

       diceware  generates  passphrases  by concatenating words randomly picked from wordlists. It supports also
       real dice for passphrase generation.

       It is based on the proposals of Arnold G. Reinhold on http://diceware.com.

       diceware also comes with a set of wordlists. The path where these lists are stored is showed with --help.

EXAMPLES

       diceware
              Create a passphrase using defaults. Outputs something like "WheelDyeHonkCanvasWitsPuck"

       diceware -d "-" -n 3
              Create  a  passphrase  with  three  words,  separated  by  dash  ("-").  Results in something like
              "Wheel-Dye-Honk"

       diceware --no-caps
              Create a passphrase without capital words. Creates something like "wheel-dye-honk".

       diceware -r realdice
              Use real dice to create a passphrase. The programm will tell you what to do (roll  dice  and  tell
              what numbers appear) and in the end present a passphrase.

       diceware -r realdice --dice-sides 20
              Use  real dice, as shown above, but this time use dice with 20 faces, instead of standard, 6-sided
              dice.

       diceware mywordlist.txt
              Create a passphrase with words from file "mywordlist.txt". The file should  contain  one  word  on
              each line.

       diceware -w en_orig -s 2
              Create  a  passphrase  with  two special chars spread over the generated passphrase and containing
              words from wordlist "en_orig". This is one of the wordlists  that  come  included  with  diceware.
              Creates something like: "Rutt[FanScoldLouiseT*nyThrob".
