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 program 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_securedrop -s 2
Create a passphrase with two special chars spread over the generated passphrase and
containing words from wordlist "en_securedrop". This is one of the wordlists that
come included with diceware. Creates something like: "PlayaBrigVer{SeesNe-tsGets".

diceware -w en_adjectives en_nouns -n 2
Create two syntactically meaningful phrases, each one consisting of an adjective
and a noun. Results in something like: "CruelAttendeesCleanCoffee".
