pp-gen

Use EFF's general short wordlist (with unique prefixes) to generate random passphrases.

https://www.eff.org/files/2016/09/08/eff_short_wordlist_2_0.txt contains 1269 memorable and distinct words for passphrases, all with unique 3-char prefixes and edit distances of at least 3.

See https://www.eff.org/deeplinks/2016/07/new-wordlists-random-passphrases for the full rationale behind the wordlist.

Each generated passphrase is printed in full, as well as with just the unique 3-char prefixes for a shorter string with the same entropy.

Run: go run pp-gen.go -len= -num=

$ go run pp-gen.go -len 6 -num 2
# Each 6-word passphrase has about 62.04 bits of entropy
krypton gothic bouquet vivacious fountain scythe :: kry got bou viv fou scy
already jiffy clubhouse doll garlic podiatrist :: alr jif clu dol gar pod

Build: go build pp-gen.go
