DarkGlass Security

First, a disclaimer: serious security is beyond the scope of this manual. Secondly, DarkGlass's main goal is to make publishing easy; security is not its primary goal. Nonetheless, it does try to make authorized access to content hard.

Hiding content
DarkGlass's basic security mechanism is to use file permissions. It is expected that DarkGlass will run as a different user from the content's owner, so that making a file non-world-readable hides it from DarkGlass. If you use DarkGlass to export your home directory, then having a umask that makes files non-world-readable by default is a good idea.
Password-protection
It may be preferable to require a password for some content. To do this, place the content in a directory that is itself protected by HTTP authentication. The details of how to do this depend on the web server; instructions for Apache can be found in its manual.
