keepassc and python-keepass
This provides command line and Python interfaces for operating on files in KeePass format v3 (used by KeePass 1.x, and KeePassX). Note, this is not the format used by the KeePass application version 2.x.
Notes of caution
Before using this code, understand the its (known) security and correctness limitations:
-
Unlike the KeePass/KeePassX GUI applications this code makes no attempt to secure its memory. Input files read in are stored in memory fully decrypted.
-
It is quite easy to display the stored passwords in plain text, although the defaults try to avoid this.
-
Specifying the master key on the command line will leave traces in your shells history and in the process list.
-
While input files are treated as read-only, keep backups of any files written by KeePass/KeePassX until you are assured that files written by this code are usable.
-
Key files are not currently supported.
Prerequisites and Installation
You will need to install the python-crypto package (providing the "Crypto" module). On a well behaved system do:
sudo apt-get install python-crypto
If installing into a virtualenv this prerequisite will be installed for you:
virtualenv /path/to/venv
source /path/to/venv/bin/activate
cd python-keepass
python setup.py install
Command line
The command line interface is run like:
keepassc [general_options] [command command_options] ...
Multiple commands can be specified and will be executed in order. They operate on an in-memory instance of the database file. An example,
keepass open -m secret file.kdb \
dump -p -f '%(username)s password is: %(password)s' \
save -m newsecret backup.kdb
Online help:
keepass -h # short usage
keepass help # full usage
Python Modules
Low level file access
from keepass import kpdb
db = kpdb.Database(filename,masterkey)
print db # warning: displayed passwords in plaintext!

The giants on whose shoulders this works stands
First, thanks to the original authors, contributors and community behind KeePass and KeePassX. I am merely a user of KeePassX.
A big credit is due to rudi & shirou (same hacker?) for the following:
Looking through KeePass/KeePassX source made my head swim. Only after reviewing their work could I get started.
