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:
