libkeepass

Python module to read KeePass 1.x/KeePassX (v3) and KeePass 2.x (v4) files.

Warning

"this code makes no attempt to secure its memory"

Requirements

see requirements.txt

KeePass 1.x support

Currently the v3 reader only goes so far, as outputting the raw decrypted data. Parsing into groups and entries is missing, but probably just needs to be integrated from Brett Viren's work.

Only passwords are supported.

No write support.

KeePass 2.x support

The v4 reader can output the decrypted XML document that file format is based on. It is also available as parsed objectified element tree.

The password elements in the XML document are protected in addition to the AES encryption of the whole database. Switching between clear text and protected is possible.

Passwords and key-file protection is supported.

Compressed and uncompressed files are supported.

There is basic "save as" write support. When writing the KeePass2 file, the element tree is protected, serialized, compressed and encrypted according to the settings in the file header and written to a stream.

Examples

import libkeepass

filename = "input.kdbx"
with libkeepass.open(filename, password='secret', keyfile='putty.exe') as kdb:
    # print parsed element tree as xml
    print kdb.pretty_print()

    # re-encrypt the password fields
    kdb.protect()
    print kdb.pretty_print()

    # or use kdb.obj_root to access the element tree
    kdb.obj_root.findall('.//Entry')

    # change the master password before writing
    kdb.clear_credentials()
    kdb.add_credentials(password="m04r_s3cr37")

    # disable compression
    kdb.set_compression(0)

    # write to a new file
    with open('output', 'wb') as output:
        kdb.write_to(output)

Testing

Make a virtualenv and install the requirements. Then run the tests script::

pip install -r requirements.txt
nosetests tests/tests.py

References

Initially Brett Viren's code was a starting point and some of his code is being re-used unchanged (https://github.com/brettviren/python-keepass).

For v4 support reading the original Keepass2 C# source was used as inspiration (http://keepass.info).

Keepass 2.x uses Salsa20 to protect data in XML. Currently puresalsa20 is used (http://www.tiac.net/~sw/2010/02/PureSalsa20/index.html) and included.

Thanks to them and all others who came before are in order.
