Currently xkcdpwd only supports English, though the framework is in place to support other languages.

Things to consider:

• Baked in dictionaries (like the English one) are easy to distribute and don't require configuraiton, but bloat the size of the binary.
• If we support user provided dictionaries, should we do any calculations to ensure that they're aren't using a dictionary that is too small?

xkcdpwd should have an option to control how many passphrases are generated at a time.

$ xkcdpwd -phrases 5
correct horse battery staple
correct horse battery staple
correct horse battery staple
correct horse battery staple
correct horse battery staple

As a user of xkcdpwd, I would like to control the case of my passphrases via a command-line option.

Options:

• capitalize first letter of all words

  $ xkcdpwd -capitalize=first
  Happy Iguana Left Users

• capitalize random letters

  $ xkcdpwd -capitalize=random
  haPPy iGuANA LeFT uSers

• capitalize all letters

  $ xkcdpwd -capitalize=all
  HAPPY IGUANA LEFT USERS

As a user of xkcdpwd, I would like to select the character used to separate words in the passphrase.

Examples:

$ xkcdpwd --separator='-'
foo-bar-baz-bam

$ xkcdpwd -s=
foo=bar=baz=bam

As a user of xkcdpwd, I would like to control the length of words used in my passphrase via a command-line option.

Examples:

$ xkcdpwd -max-length=10
happy iguana left users

$ xkcdpwd -min-length=10

• minimums and maximums that reduce the size of the dictionary such that entropy falls below 30 bits will result in an error

# max word length is 18
$ xkcdpwd -max-legnth=23
error: dictionary cannot support more than 30 bits of entropy

# min word length is 4
$ xkcdpwd -min-length=3
error: dictionary cannot support more than 30 bits of entropy

Select dictionary language based on the user's system locale or a command-line flag.

Examples:

$ export LANG=fr_FR.UTF-8
$ xkcdpwd
content iguane gauche utilisateurs

$ xkcdpwd -lang fr
content iguane gauche utilisateurs

As a user of xkcdpwd, I would like to control the number of words in the passphrase via a command-line option.

Examples

$ xkcdpwd -words=5

$ xkcdpwd -words=2
error: cannot generate a passphrase with less than 30 bits of entropy
