This could be a great alternative if you have used TrueCrypt encrypted volumes.
I’ve been a TrueCrypt lover for a long time, even after it was allegedly killed. But now I’m starting to think that it’s not a good option for long term safekeeping of my memories. At time point in a future release of Linux if dependencies for TrueCrypt stop working that’s death to my archives. Fortunately we have LUKS since 2004! After using LUKS for a couple of years I think it’s very reliable.
