pwgen-passphrase
Secure wordlist-based passphrase generator
Description
Use pwgen-passphrase to generate secure (yet easy to remember) random passphrase from wordlist.
See legendary xkcd: Password Strength comic strip for more details ;-)
Included wordlists are:
- diceware (English: 7776 words)
- eff-long (English: 7776 words)
- eff-short (English: 1296 words)
- eff-short2 (English: 1296 words)
- bip0039 (English: 2048 words)
- skey (English: 2048 words)
- cracklib-small (English: 52875 words)
- aspell-en (English: 123232 words)
- aspell-cs (Czech: 304607 words)
Requirements
- Python 3
- Optional: PyQt (for copying generated passphrase to clipboard)
- Optional: regex
(for better regex filtering, e.g.
^[\p{Ll}]+for Unicode lower-case letters only)
Usage
Run pwgen-passphrase --help to see all available options.
Example:
[randall@xkcd.com ~] pwgen-passphrase -w cracklib-small -l 4 -t correct horse battery staple Statistics: =========== Number of words in passphrase: 4 Wordlist length: 52875 words Passphrase strength (entropy): 62.8 bits Passphrase length: 28 chars Length of equivalent case sensitive alphanumeric password: 11 chars Length of equivalent all ASCII printable characters password: 10 chars
