Hi, does anybody know of any tool that would allow me to have all files store in a folder automatically encrypted? or some similar capability?
i assume you are referring to something that windows does with a particular folder?
anyway, AFAIK, you can't do this with ufs. you would have to figure out a way to use crypt (or another 3rd party binary) in a cron'd fashion to encrypt your folder. however, that is not to say the original source folder would be encrypted.
i know there are plans for encryption to be integrated with zfs but i don't think it is fully released to opensolaris yet. Someone please correct me if i'm wrong here.
my guess would be to have your storage NAS/SAN look into encrypting. even then, i'm not sure if it would be what you are looking for.
You are right, ZFS internal encryption project isn't in OpenSolaris dev builds yet. ZFS on disk encryption support (Project zfs-crypto.WebHome) - XWiki
A workaround is to take advantage of lofi encryption combined with ZFS:
