A command-line password manager written in Haskell.
It uses external programs for most of its tasks:
gpgfor encryption of your password database (but you can easily adjust it to use
opensslwith AES and a master password)
xdg-openfor interaction with your web browser
xclipfor interaction with your X selection
pwgenfor generation of user names and passwords
shredif you want to edit your password database with a text editor
Currently only Unix-like systems are supported.
Any questions/comments/patches are gladly welcome!
How to use pwsafe.
Adding a new entry to the password database
Let's say you want to create an account on the website http://www.niftyservice.com. Then you would proceed like this:
Only once: setup gpg and generate a keypair. pwsafe uses the gpg default keypair to decrypt and encrypt your password database.
$ gpg --gen-key
Point your web browser to http://www.niftyservice.com and navigate to the sign-up page where you have to enter your new login credentials like username and password. Don't enter anything yet. Usually, these pages have at least three input fields:
- enter your desired username
- enter your desired password
- repeat your desired password
In a terminal, call pwsafe like this:
$ pwsafe -a http://www.niftyservice.com You need a passphrase to unlock the secret key for user: "Some Body <email@example.com>" Waiting for one selection request.
pwsafe has generated a random username and password for you, and added it to the password database. At this point, pwsafe blocks and waits for a paste request. In X, you do that with your middle mouse button.
In your web browser, middle-click on the "username" field. pwsafe pastes the username it has generated for you.
pwsafe now waits for you to paste the password two times. Middle-click on the "password" field, then again in the "repeat password" field.
pwsafe exits, because it's job is done for now. Fill out the rest of the fields in the web form to your liking.
Looking up a password in the database
If you want to log in to niftyservice again, proceed as follows.
Call pwsafe like this
$ pwsafe -q nifty You need a passphrase to unlock the secret key for user: "Some Body <firstname.lastname@example.org>" Waiting for one selection request.
The term nifty must match exactly one entry in your password database. If you have two entries, one for niftyservice and one for niftycatpictures, pwsafe exits with an error. Make the term long enough to be unambiguous.
At this point, pwsafe has opened the website that corresponds to the entry in your default web browser. To configure your default web browser, consult the documentation of xdg-open and update-alternatives.
Switch to your browser window and navigate to the login page.
Middle-click on the "username" field.
Middle-click on the "password" field.
pwsafe exits, and you can proceed with the login.
Changing or deleting an entry in the database
pwsafe does not have commands to edit entries in your database. Instead, it
fires up vim with the complete decrypted database for you to edit it. pwsafe
decrypts your database to a temporary file, loads this file in vim with
sensible defaults (no backupfile, no vimfile, no swapfile, etc). Once you are
done editing, pwsafe encrypts the file again and calls
shred to securely
delete the decrypted copy. If you are using an SSD, shred is useless, so you
better be using hardware encryption.
Currently, only vim is supported for database editing.
An entry in the database has a symbolic name and three fields: user, url and password.
[www.niftyservice.com] user=rwDJEs5J password=XArG9R4QBDwR7ceCVjyV url=http://www.niftyservice.com
Only the "name" and "password" fields are required. "user" and "url" are optional. If the url field is not present, pwsafe will not invoke your web browser on query. If the user field is not present, pwsafe will only provide the password to paste on query.
Command line options
Usage: pwsafe [OPTION]... --help display this help and exit -a URL --add=URL add a new entry to the database; the password is always automatically generated; the username is generated unless --user is specified -q TERM --query=TERM lookup a password, the term must match exactly one entry -l[TERM] --list[=TERM] list all entries matching the given term -e --edit invoke vim to edit the database using sensible defaults (no backup, no swapfile etc) --dump dump database to stdout --lock acquire write lock for database --unlock release write lock for database --dbfile=FILE file where passwords are stored; defaults to ~/.pwsafe/db --user=USER specify a username to be used for a new entry; this option is to be used with --add -n NUMBER copy password n times to clipboard; defaults to 1 --password-only only copy password to clipboard
pwsafe is primarily here to serve my needs. If we can extend it in a way that makes it more useful for you and still serves my needs, even better!
Make sure that the test suite passes with your changes and add tests for new code.
Running the tests
First make sure that you have the latest version of
$ cabal update && cabal install cabal-install
Make sure that
~/.cabal/bin/ is on your
Run the tests:
$ cabal install --enable-tests --dependencies-only $ cabal test
Running the tests during development
During development you want to run the test with GHCi. This is much faster and provides better feedback:
$ chmod og-w .ghci $ ghci test/Spec.hs *Main> :main
After making changes, run:
*Main> :reload *Main> :main
