Drive encryption (not loop, not a new partition)
For quite a while, I've been playing with the idea of encrypting some parts of my hard drive. The problem is, I'm unable to find a documentation that suits my needs.
What I want is to simply take my existing partition and to encrypt it. All documentation I have found tells me how to either create an encrypted loopback device (don't wanna), or how to create a blank encrypted partition, where the conversion to an encrypted partition destroys all data on the partition itself (don't wanna either).
Does anybody know a way to just make a non-encrypted partition encrypted?
Thanks a lot in advance,
