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 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.
