Encryption feature added into EXT4 in Linux kernel 4.1

Ted Ts’o and Michael Halcrow have added encryption into the EXT4 file-system in Linux Kernel 4.1. It works by encrypting at the directory tree level and uses cryptographic keys based on AES-128-ECB .

Once the code has matured, and stood the test of time, this could be a very popular feature. I will be closely watching how this takes off considering the large EXT4 userbase -> Android eco-systems, many embedded Linux devices, Linux desktops and Linux servers.

Imagine a world with encryption by default.
