Cryptography for Trac


This plugin supports cryptographically backed functions in Trac. The level of privacy offered based on these functions is different compared to other privacy-related plugins:

These plugins attempt to protect only some part ('realm') of Trac's content, they do not differentiate in terms of protection strength.

This is WiP and in a very early stage. Nevertheless testers are very welcome. Reports about your expectations as well as your findings will help them mature and match your needs.

Regular content is accessible as per applicable TracPermissions settings, and users can save content without additional protection regardless of other options, if available at all. Since it is the same for any setup, it's not worth mentioning this type of content in the table above.

Ultimate privacy doesn't assume any trust outside of the Trac system software, and this includes plugins. This kind of inherent Trac content protection is neither available nor planned yet.

Likely there are not many web services that grant at least strong protection without installation of special software at client side. And if so, they certainly do not offer Trac's documentation and bug-tracking capabilities.
