HAMMER itself doesn't provide any encryption support. Our transparent
encryption is file-system agnostic (you can also encrypt your swap and
UFS, for example) and is implemented in the device mapper (dm) as
dm_target_crypt. To use it, you should check out the cryptsetup man
page, or for that matter, any linux dm-crypt disk encryption tutorial,
since we have the same *userland* tools.

The installer also has support for creating encrypted volumes on install

Hope that helps,
