No, cgd is a cryptographic device, not a file system. A cryptographic file
system would encrypt the data in the files, but not necessarily the meta
data. Also, a cryptographic file system could use different keys for
A file system would be more for a case where physical security isn't a
strong issue but protecting one user from another is. cgd is best for a
case where protecting one user from another isn't a big deal, but phsyical
cgd is great for your laptop in case it gets stollen. A cryptographic file
system is great for a file server that needs to protect data from
different users. Say a computing center that performes service work
(computations, simulations) for competing companies.
They both have their place.
