usage: nodice [-h] [--words WORDS] [--entropy ENTROPY] [--spacer SPACER] [--dice DICE] [--sides SIDES] [--show-rolls] [--file FILE] [--delimiter DELIMITER] [--verbose]
Generate diceware passphrases from wordlists.
options:
-h, --help show this help message and exit
--words WORDS, -w WORDS number of words (default: `5`)
--entropy ENTROPY, -e ENTROPY set minimum bits of entropy
--spacer SPACER, -s SPACER separate words with a spacer (default: ` `)
--dice DICE, -d DICE number of dice per word; ignores --file and --entropy options
--sides SIDES, -D SIDES number of sides per die (default: `6`)
--show-rolls, -r show dice rolls only
--make-custom, -m generate keys (dice rolls) for custom wordlist
--file FILE, -f FILE diceware dictionary file (default: `wordlists/eff_large_wordlist.txt`)
--delimiter DELIMITER, -t DELIMITER dictionary delimiter (default: $'\t')
--verbose, -v show entropy information- Running
nodiceorpython -m nodicewithout any options falls back to defaults: 5 random words fromeff_large_wordlist.txt.

> 12 random words from a 2048-word list yield 132.0 bits of entropy.It is possible to use custom wordlists, either delimited alongside their corresponding dice rolls, or simply a bare list of words, as in the examples below respectively.
- For delimited wordlists, the defaults apply (i.e., delimiter and number of sides), otherwise they would need to be passed in as arguments.
11111 abacus
11112 abdomen
11113 abdominal
11114 abide
11115 abiding
11116 ability
...
- In the case of a bare wordlist like the one below, dice roll keys for a perfect-power-length wordlist will be generated when possible using smaller than 10-sided dice, whereas other length wordlists are unhandled for now.
abacus
abdomen
abdominal
abide
abiding
ability
...
Using the --make-custom flag with a bare wordlist creates the wordlist alongside the corresponding keys (dice rolls):
$ nodice --make-custom -t, -f bare_wordlist.txt | tail
