ecryptfs == privacy

ecryptfs == privacy

Simple and nice way to protect your documents in linux.
Install ecryptfs by executing the following command:
$ sudo apt-get install ecryptfs-utils

Create a directory where you want to put those private documents. For example I will create a folder in my home, named "Personal", and set the permission only to owner.
$ mkdir ~/Personal
$ chmod 700 ~/Personal

Mount that directory as eCryptfs filesystem.

$ sudo mount -t ecryptfs ~/Personal ~/Personal
I chose passphrase, aes, and 16-bit. For plaintext passthrough I chose "no" (no non-ecrypted files allowed in the mount).

Move, copy, create all private documents into ~/Personal directory.

When done, umount ~/Personal by executing:
$ sudo umount ~/Personal

All the files inside that directory can not be opened unless you mount it as ecryptfs filesystem.

Next time you mount, use the following command, so it will only ask for passphrase.
$ sudo mount -t ecryptfs ~/Personal ~/Personal -o key=passphrase,ecryptfs_cipher=aes,ecryptfs_key_bytes=16,ecryptfs_passthrough=n
