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".
