LXer: File System Encryption on CentOS 6
Published at LXer:
CentOS 6 now includes eCryptfs which provides the ability to encrypt data and files on a per-file basis instead of the entire disk as in block encryption. The eCryptfs system sits on top of the current file system to provide the encryption layer, that is why it is known as the pseudo-file system. The file operations which are sent to the underlying file system are intercepted by eCryptfs and encrypted.
