A flexible and scriptable password generator which generates strong passphrases, inspired by XKCD 936:
$ xkcdpass > correct horse battery staple
Describe how to use this command.
--wordfile WORDFILE, -w WORDFILE
Specify that the file WORDFILE contains the list of valid words from which to generate passphrases.
Generate passphrases containing at least MIN_LENGTH words. (Default: 5)
Generate passphrases containing at most MAX_LENGTH words. (Default: 9)
--numwords NUM_WORDS, -n NUM_WORDS
Generate passphrases containing exactly NUM_WORDS words. (Default: 6)
Generate and output a passphrase, query the user to accept it, and loop until one is accepted.
--valid_chars VALID_CHARS, -v VALID_CHARS
Limit passphrases to only include words matching the regex pattern VALID_CHARS (e.g. '[a-z]').
Report various metrics for given options.
--acrostic ACROSTIC, -a ACROSTIC
Generate passphrases with an acrostic matching ACROSTIC.
--count COUNT, -c COUNT
Generate COUNT passphrases. (Default: 1)
--delimiter DELIM, -d DELIM
Separate words within a passphrase with DELIM. (Default: ' ')
--separator SEP, -s SEP
Separate multiple passphrases with SEP. (Default: U+000A LINE FEED)
--case CASE, -C CASE
Set the case of each word in the passphrase by method CASE. (Default: lower)
Valid CASE values are alternating, upper, lower, first, random.
Generates one passphrase with the default options. Example output:
pinball previous deprive militancy bereaved numeric
xkcdpass --count=5 --acrostic='chaos' --delimiter='|' --min=5 --max=6 --valid_chars='[a-z]'
Generates 5 passphrases, all from lower-case words and meeting the acrostic “chaos”, delimited by the “|” character. Example output:
collar|highly|asset|ovoid|sultan caper|hangup|addle|oboist|scroll couple|honcho|abbot|obtain|simple cutler|hotly|aortae|outset|stool cradle|helot|axial|ordure|shale
The xkcdpass command invokes the Python program xkcd_password.py.
The inspiration for the program's purpose is the XKCD 936 “Password Strength” cartoon.
