Another test version before it will be released on Harbour:

New in Cargo Dock 0.2.1.105:

- Passwords are saved Blowfish-encrypted

If you have already saved WebDAV passwords with an earlier test version of Cargo Dock, you will be required to set them again. To be more safe, remove the service entry from the settings first, so that the plain-text password will be removed from the configuration file; otherwise it will stay there.

Passwords are by default encrypted with an undisclosed default passphrase that is not part of the open source distribution.
This is only safe until someone discovers it in the executable.

To be more secure, you can set a custom pass phrase that is not stored anywhere (and has to be entered once per session).
