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.
Examples
diceware
Create a passphrase using defaults. Outputs something like "WheelDyeHonkCanvasWitsPuck"
diceware-d"-"-n3
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-rrealdice
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-rrealdice--dice-sides20
Use real dice, as shown above, but this time use dice with 20 faces, instead of standard, 6-sided
dice.
dicewaremywordlist.txt
Create a passphrase with words from file "mywordlist.txt". The file should contain one word on
each line.
diceware-wen_securedrop-s2
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-wen_adjectivesen_nouns-n2
Create two syntactically meaningful phrases, each one consisting of an adjective and a noun.
Results in something like: "CruelAttendeesCleanCoffee".
