Welcome to the KWoodhammer Environment!
The current version is 1.87 (Alpha 0). You can download it here. But be sure this version won't work, as it is intended for preview only.
The 1.x KWoodhammer
This is the version 1.00. It is defunctional in all parts of decryption, but provides a useful encoding for small texts and features already plenty of options and configurations.
The old KWoodhammer docs are currently updated to reflect the improvements of the new version.
