Manage passwords in a git backed encrypted gnupg database with LDAP support

Project description

Build Status PyPI MIT licensed


pwmanager is a python script for storing passwords, searchable by hostname and user, in a gnupg encrypted git backed database. It can encrypt to multiple keys and also fetch keys from LDAP, allowing you to easily and securely share and version control passwords with others. Useful for both personal and group-wide password storage and sharing.

Where to get it

The latest release is available at PyPI:

Source code repository is at github:

Basic installation

Quickest and easiest is to install using pip3 from PyPI as your local user:

pip3 install --user pwmanager

You can also install the latest development version directly from the github repository:

pip3 install --user git+git://

Some options need to be set in the configuration file. A sample pwmanager.conf (pwmanager.conf.sample) is included in the package. pip3 will install it in the pwmanager/data subdirectory of the appropriate python site-packages directory. It should be put in $HOME/.pwmanager/

The standard location for your password repository is $HOME/.pwmanager/data

pwmanager requires python3 >= 3.4 and some extra packages, see for details. Python 2.x is not supported.

Using it

Getting help

pwmanager -h

Help on actions is available by appending -h:

pwmanager add -h

Storing passwords

Adding the password secretpass for the account root on to the database:

pwmanager add root secretpass

If you leave out secretpass, pwmanager will prompt you for the password.

Retrieving passwords

Retrieving the password stored above:

pwmanager get root

Note pwmanager get matches both the hostname and username as substrings and if you do not specify a username it will list all accounts, so all of these will find the above account (and maybe others):

pwmanager get roo
pwmanager get oot
pwmanager get r
pwmanager get r
pwmanager get
pwmanager get com
pwmanager get h

Synchronizing with others

pwmanager will always update from and push to origin when there is an origin git remote configured. git adds origin automatically if you clone an already existing repository, but you need to add it manually if you initialize it yourself or use pwmanager init.

To add a remote repository later, use the normal git way:

cd /path/to/datastore
git remote add origin URL

In normal operation, pwmanager will, before doing anything, always fetch and rebase on the latest origin/master, and will push to origin/master afterwards. It will also retry this up to five times in case multiple people are in a rebase-race and pushing at the same time. However, if you just added a new origin remote it's a good idea to manually run:

git fetch origin
git rebase origin/master

If any of the two commands above fail, you need to fix whatever git complains about or pwmanager will not work.

How are the passwords stored?

(aka When the script doesn't work and you desperately need a password)

All passwords are stored in separate files, one per password, in your datadir. They are encrypted using GnuPG to all keys you configured to use, so if you have a suitable key available in your local gnupg keyring and you want the password for 'user' on 'host', you can do so by just running gnupg:

gpg -o - -d datadir/host/user.gpg

If this fails, ensure you have your secret key in your gnupg keyring.

Why is every password in a separate file, you ask? Because that enables replacing individual passwords without having access to any secret key. This allows automated password rotation, for example.


Decryption failed

gnupg could probably not find your secret key. Make sure your secret key is available in your standard keyring in ~/.gnupg and that you're running the latest gnupg 2.x series.

For debian stretch you need to install python3-gnupg from stretch-backports.

If your system defaults to gnupg 1.x and your gnupg 2.x binary is called gpg2, set gpg_path = gpg2 in the [gnupg] section of pwmanager.conf.

RuntimeError: No recipients to encrypt to!

You haven't added any key fingerprints in pwmanager.conf and haven't configured any other data source. There are simply no public keys configured to encrypt to.

"I don't understand how to get the LDAP stuff working at all"

pwmanager currently assumes you have a group (objectClass: posixGroup) with a memberUid attribute for every member. Those should map to whatever you've set as user_attr in pwmanager.conf.

Next, pwmanager assumes the user has the attribute you've set as key_attr, which should be the DN of a PGP keyserver compatible entry under key_dn, normally ou=PGP Keys,dc=company,dc=com.

The same LDAP server must be able to act as a PGP compatible keyserver (hint: gpg --send-keys should work). Also, don't forget to uncomment the [ldap] header in pwmanager.conf.

Known issues

  • pwmanager does not call mlock(), mostly because doing so would require calling mlock() for the entire ~5 MB python binary.

  • pwmanager currently does not support multiple git remotes. That should probably be implemented, for numerous reasons.
