Easy to use command line based strong passphrase generator.

Implemented as a self contained perl script that should work on many unix like systems.

The passphrase-generator defaults to only 3 words instead of the 4 suggested by XKCD, but uses a larger dictionary found in many unix like systems at /usr/share/dict/words. It also provides estimates for the entropy of the generated passphrases. The randomization is based on /dev/urandom and SHA1.

See http://xkcd.com/936/ for an entertaining take on passwords vs. passphrases.

Features

  • Provides estimates of passphrase entropy
  • Uses /dev/urandom as randomness source
  • Options to adjust generated passphrases
  • Uses /usr/share/dict/words as a dictionary
