WARNING: This is an alpha release, bugs and edge cases are expected. As this has the potential for stopping users from logging in, extensive testing should take place before deploying into production.

Crypt 2 is an authorization plugin that will enforce FileVault 2, and then submit it to an instance of Crypt Server. It makes use of Swift, so is theoretically compatible with 10.9 +, however in it's present alpha quality state, it has only been tested on 10.11.

• Uses native authorization plugin so FileVault enforcement cannot be skipped.
• Escrow is delayed until there is an active user, so FileVault can be enforced when the Mac is offline.
• Administrators can specify a series of username that should not have to enable FileVault (IT admin, for example).

Preferences can be set either in /Library/Preferences/com.grahamgilbert.crypt.plist or via MXC / Profiles.

The ServerURL preference sets your Crypt Server. Crypt will not enforce FileVault if this preference isn't set.

$ sudo defaults write /Library/Preferences/com.grahamgilbert.crypt ServerURL "https://crypt.example.com"

The SkipUsers preference allows you to define an array of users that will not be forced to enable FileVault.

$ sudo defaults write /Library/Preferences/com.grahamgilbert.crypt SkipUsers -array-add adminuser

Crypt 2 couldn't have been written without the help of Tom Burgin - he is responsible for all of the good code in this project. The bad bits are mine.
