Encrypting Files

[mfaridi]

I test steghide
this port dose not support large file and I think I can not use it .

You can easily find high quality 3+ Gigapixel images on flicker.

You can also use a image instead of a ``real'' filesystem, for example on FreeBSD:

First create a image, 100MB in this case:

$ dd if=/dev/zero of=secret.img bs=1024K count=100

Next use mdconfig to create a /dev entry:

# mdconfig -at vnode -f secret.img

Next you can follow the normal stept for creating an encrypted filesystem (i.e. Killasmurf's FreeBSD + Geli), using md0.

You can use
# mdconfig -du0
to detach the device.

This is much more flexible and faster, and you can set it up any time, no need to newfs stuff ...
