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".
