Log message:
swap encryption for UVM, option UVM_SWAP_ENCRYPT.  needs to be enabled
via sysctl.
Pages are encrypted with the Blowfish encryption algorithm, the key
is initialized randomly on first swap out, ensuring that entropy has
accumulated in the kernel randomness pool.  Eventually, swap encryption
will be decided on a process by process basis, e.g. a process that reads from
a cryptographic filesystem will enable swap encrypt for its pages. okay
