* dispass.el
Generate and disperse/dispell passwords.
~dispass.el~ is an emacs wrapper around [[http://dispass.babab.nl][DisPass]].
** Installation
Place this file somewhere on your filesystem, either in your
~load-path~ or somewhere else which you will have to add to your
~load-path~, like so:
#+begin_src emacs-lisp
(add-to-list 'load-path "/location/of/dispass.el")
#+end_src
And then ~load~, ~require~ or ~autoload~ it in your emacs init file, for
example:
#+begin_src emacs-lisp
(require 'dispass)
#+end_src
/Or/ if you have ~package.el~ with the Marmalade and/or MELPA
repositories set-up you could use ~package-install-file~.
** Customization
~dispass.el~ offers a few customizable settings, all of these can be
changed using the Emacs customization interface, or of course your
Emacs init file:
- =dispass-default-length= :: The default length of passprases
generated by DisPass, when no length has been specified in
the labels file for a given label.
- =dispass-executable= :: The place where the ~dispass~ executable
script is located.
- =dispass-labels-executable= :: The place where the ~dispass-labels~
executable script is located.
- ~dispass-file~ :: The location of your DisPass label file.
** Usage
Using dispass.el is simple, once installed.
*** Creating and regenerating passphrases
To create a new passphrase use the command ~dispass-create~, to
regenerate a previously stored one use ~dispass~.[fn:1]
When a numeric argument is used when calling either =dispass-create=
or =dispass=, that argument is sent to the dispass program along
with the ~-l~ switch. This cuts the length of the password to that
many characters. For example:
#+begin_example
C-5 M-x dispass<RET> test<RET> test<RET>
#+end_example
will generate a passphrase of 5 characters for label "test" and
password "test".
Once a passphrase has been generated it is inserted into the kill
ring and the system's clipboard so it can be easily inserted into
any password field, unfortunately this also makes the generated
passphrase easy to see in plaintext in the =kill-ring= variable,
though.
*** Listing/managing labels
With the command ~dispass-list-labels~ you can get an overview of
the labels you have stored in your labels file, along with their
stored meta-data.
Some label management functions are available in this mode,
namely adding and removing labels. See the mode description for
a list of keybindings.
Apart from the keybindings available in the list buffer there are
also the commands ~dispass-add-label~ and ~dispass-remove-label~
which add and remove a label respectively.
* Footnotes
[fn:1] There is no requirement to first call ~dispass-create~ before
using ~dispass~, but the former asks for confirmation of the password
and newer version of DisPass will automatically store the label and
its meta-data (such as length) in your labels file.
