Even though this will probably only appeal to a small fraction of this forum's userbase, I would like to introduce DistantKeys: an easy-to-use deterministic key generator, primarily designed for self-discipline purposes. Use it to set the configuration password in NetNanny, K9 BlueCoat, etc once you are happy with your setup and are ready to "freeze" it.

Thanks for your feedback. Notes: This is a preview edition with only the core functionality available. Some menu items are not implemented yet. The default seedless mode is not security-oriented. Do not use those keys to protect sensitive data. This version expires on July 31, 2015. However, early users will be able to request a free lifetime license! PS: This app will get a proper launch and webpage soon enough.
