Emacs wrapper for DisPass
Emacs Lisp
Latest commit b6e8f89 Feb 2, 2014 @ryuslash Add dispass-insert
Does the same thing as the `dispass' command, except it inserts the
results into the current buffer, instead of copying them into the
clipboard. This is useful when Emacs asks for a password and thus skips
the clipboard and `kill-ring'.

Using the universal argument is not possible because the prefix argument
is already used to determine the required length of the generated
passphrase.

dispass.el

Generate and disperse/dispell passwords.

dispass.el is an emacs wrapper around 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:

(add-to-list 'load-path "/location/of/dispass.el")

And then load, require or autoload it in your emacs init file, for example:

(require 'dispass)

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.

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:

C-5 M-x dispass<RET> test<RET> test<RET>

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.

Something went wrong with that request. Please try again.
