A small tool that helps you regain access to your KeePassXC password database in case you have it protected with YubiKey challenge-response and lost your key.
Currently supports KDBX4 databases with Argon2 hashing.
## Building
Tested with Go 1.13. Just run `go build`.
## Usage
What you need:
* your KeePassXC database
* your challenge-response secret. This cannot be retrieved from the YubiKey, it needs to be saved upon initial configuration of the key.
It will prompt for the challenge-response secret. You will get a keyfile at the specified destination path. Then, to unlock your database in KeePassXC, you need to check "key file" instead of "challenge response" and load the file.
