[SunRescue] Encrypted file systems?

[Tom]

Linux has pretty robust support for encrypted file systems - however, I'm 
trying to see if Solaris has anything similar?

I'm under NDA, so I have to be careful what I say :-) but let's imagine you 
have some portable UltraSparc based machines ;-) let's also imagine that you 
have some PCMCIA hard drives, that contain sensitive data.

Now, under Linux, I could create an encrypted volume (as a single file) on 
that PCMCIA drive, and then, once the drive itself has been mounted, I could 
mount the encrypted volume (having entered the approprite pass phrase, and 
having the proper access to the right keys).

Anyone done something similar under Solaris? The trick, as I can see it (and I 
may be wrong) is that Linux has kernel support for encryption algorithms that 
are used by the loopback device when creating the encrypted volume.

How does Solaris deal with that? Would you need kernel support, or can the 
loopback device support different cyphers directly?

As you can see, I'm a bit at sea on this one ;-) Any help is *really* 
gratefully recieved...

Thanks,
TOM
