Examples using the built-in word list

One segment

Each invocation generates a different random password consisting of a built in word and a number.

$ obj/pwdgen --builtin-wordlist --segments=1
star-29660
$ obj/pwdgen --builtin-wordlist --segments=1
thoracic-55658
$ obj/pwdgen --builtin-wordlist --segments=1
peptic-30298

Multiple segments

$ obj/pwdgen --builtin-wordlist --segments=2
perfect-29787-Dendrite-38203
$ obj/pwdgen --builtin-wordlist --segments=3
vein-47519-Bone-52061-jimsonweed-16299
$ obj/pwdgen --builtin-wordlist --segments=3 --separator=~

Key Derivation

Key derivation function generates a fixed length key given a cleartext password. The complexity could be increased by asking for multiple iterations.
