How do I encrypt my home partition?
EDIT: Its not a duplicate. "How do I encrypt my home partition?" is old and does not mention anything about EXT4.
I have installed Ubuntu 11.04.
At the time of installation I did not encrypted my home partition, but now I feel the need of it. How do I encrypt my home partition?
Please note, I have ext4 file system.
Once encrypted will I be able to recover my data in case of OS Crash (which occures very rarely)?
