Does anyone know if the NCryptfs source code is available at all. I tried google as well as the Stony Brook's site but all I could get was the white paper. Will appreciate any pointers.

thanks,

Are these the unionfs people?

A brief history of the recent unionfs debacle (it comes from Stony Brook also) -- it was to be included in kernel 2.6.20, but was found to have a fatal/unresolvable bug and was pulled for "complete rewrite". I was forced to switch to a userspace FUSE-based thing called 'funionfs' that needs time delays (3 seconds?) after mounts before it can be used without errors. Knoppix had to switch to 'aufs' (a rewrite of unionfs). Apparently the unionfs people assumed they would be included in the kernel so the previous method of unionfs install (kernel patches) was neglected/broken and could not be applied to 2.6.19 - 2.6.19.2.

I will not be eagerly awaiting future Stony Brook "FiSt"-based filesystem offerings.

ah...didn't know about that.

ah...didn't know about that. It sure doesn't sound too good. I have been more interested in the crypto file systems developed through FiST. Cryptfs, NCryptfs and eCryptfs are the available options. Of which I could get my hands on the code for Cryptfs and eCryptfs but not NCryptfs. eCryptfs claims to be the enterprise class crypto FS and does perfom as stated (as per my minimal testing). So I wanted to compare it with NCryptfs but as mentioned earlier the code is nowhere to be seen!!

Can you send me the source

This is my email:hrrconan@hotmail.com
I'll greatly appreciate your help!Thanks

Download the latest fistgen

Download the latest fistgen source from ftp://ftp.filesystems.org/pub/fistgen.
You can then build cryptfs using the cryptfs.fist available under $fistgen_src/cryptfs/.
