Hi,

I went through your readme. Some questions.

1. How are you encrypting the files? Is it done by the encryptfs or you are doing it in your module.

2. How can the user selectively encrypt the files in the system.

Hi Rishi,

Sorry about the fuzziness.

#1 I plan to do the encryption in my module, but encrypting
functions aren't added to it yet. As I mentioned in readme,
module now just simply pass-through operations to the original
file system.

#2 It seems that the user cannot select specific file to encrypt
inside one directory :-( . However he may specify a directory
then we can encrypt all the file inside it. Namely, the granularity
is directory, not file. Besides, subdirectory is not supported at
present.

Why does it even matter - inode vs directory? Is it because you store the encryption metadata in the dirent and not the inode?

Freeman

Hi Sandeep,

Actually I haven't got that far...
However as I planed it, I don't want involve the user too much－
just to keep simple. I plan to build a safe box, and people throw
personal things into it. That's all.
I want to use it with Android devices. Will complex implementation
build barrier for ebedded system?
Any suggestions?

Freeman Zhang
