KeepassXC-Pwned

Project Status

The functionality to check passwords again the HIBP database has been built into keepassxc since version 2.6.0 (Database > Database Reports > HIBP). This project should still work on keepassxc versions <2.6.0, though fails due to what I assume is a change in the specification for the keepassxc-cli export post version 2.6.0. I don't plan to update this to work with keepassxc 2.6.0 seeing as the functionality this offered is now built-in. This can still be used as a utility module to check passwords against the HIBP database:

In python code:

from keepassxc_pwned import check_password
check_password("password")

Note: check_password doesn't attempt to do any rate limiting.

or, by entering the password manually:

$ python3 -m keepassxc_pwned
Password to check:
Found password 1054 times!

This checks a KeePassXC database against previously cracked haveibeenpwned passwords.

Requirements

• keepassxc-cli binary (typically installed with KeePassXC)
• python 3.6 or above

Install

pip3 install keepassxc-pwned

Run

Run: keepassxc_pwned ~/database.kdbx

Usage: keepassxc_pwned [OPTIONS] DATABASE

  passwords

                        sha1 hashes.

  -v, --verbose         Print debug messages
  -q, --quiet           Don't print status messages, just the summary
  --keepassxc-cli PATH  Specify a different location for the keepassxc-cli
                        binary

  --help                Show this message and exit.

Privacy concerns

This tool only transmits the first 5 characters of the SHA-1 hash of your passwords. You can read more about that here.

Troubleshooting

If keepassxc-cli is named something else on your installation of KeepassXC, specify the full path by providing the --keepassxc-cli flag, like: keepassxc_pwned --keepassxc-cli "$(which keepassxc.cli)" ~/Documents/updated_database.kdbx

If you get the following error while using keepassxc-cli:

dyld: Library not loaded: /usr/local/opt/quazip/lib/libquazip.1.dylib
  Referenced from: /usr/local/bin/keepassxc-cli
  Reason: image not found
Abort trap: 6

... installing quazip should fix that:

• brew install quazip (Mac)

• sudo apt install libquazip-dev (Linux)

If keepassxc-cli fails with an error message like "Invalid Command extract.", the command was changed in KeePassXC 2.5.0, and is now called export. Upgrade KeePassXC to the latest version, and try again.
