one way: consider using vnconfig
another way: see cfs (ports security/cfs)

> And if so, how can I create one?

for vnconfig:
# dd if=/dev/zero of=mycryptedfile.fs bs=1024 count=1024
to create a 1M file (sure you'll prefer a bigger size...)
# vnconfig -cvk svnd0 mycryptedfile.fs
enter you (secret) key (be sure to be the only one on the host...)
# newfs /dev/svnd0c
# mount /dev/svnd0c /mount/point
# cd /mount/point
here you are :-)

for cfs: consult man pages bundled with the package.

hopefully this points you where you are looking...
