Need Assistance on using xattr

[Parag Amritkar]

i,We r working on inherent encryption decryption in kernel,nw we r stucked
upon where to store key of encryption. Can we store it in xattr of that file
? Will it be secure? Please reply as early as possible. This is our Project
Abstract->

Abstract:

In today's world securing file data is very important. The proposed Secure
File System (SecFS), we will be providing file data security using
cryptographic techniques in a transparent and convenient way. The proposed
SecFS pushes encryption services into the Linux kernel space, mounting it
between the virtual file system layer and underlying file system. After
SecFS is integrated with the Linux operating system (OS), it enables OS to
provide file data security as its inherent functionality. SecFS requires
that the user creates a directory and name it with the prefix 'ecrypt' to
store the encrypted file data, such as ecryptdir. Any directory on the
system with the prefix 'ecrypt' will basically tells the system that the
newly created directory will contain encrypted data. All files destined to
be saved on this directory will be transparently encrypted on the fly
without any user intervention. SecFS will be fully compatible with all
underlying storage file systems.

Please reply soon.

   Yours Sincerely
