Ted Ts'o at Google has implemented EXT4 encryption support that will likely be baked into the next Android "M" release and is being worked toward for mainline inclusion in the upstream Linux kernel.

Ted published the twenty-two patches earlier this month for implementing encryption support into EXT4, complete with file-name and symlink encryption. The patches were developed by Ted Ts'o and Michael Halcrow.

There's just over three-thousand new lines of code in the kernel for implementing this encryption support. The design and implementation might end up getting shared too with the new F2FS Flash-Friendly File-System.

The patch series with more information on the EXT4 encryption support can be found via the EXT4 mailing list.
