Ubuntu Manpage: diceware - create passphrases

NAME

       diceware - create passphrases

SYNOPSIS

       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.

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".
