Thanks a lot for the answers, but i'm really worried about the the performance, lets say i want to encrypt a 20Gb /home partition, i don't want to wait +15 minutes to enryption process finish every time i shutdown the laptop, is that the way it works?, or is faster?, i've never used it
The contents of the disk are not decrypted and encrypted en masse at startup and shutdown. The on-disk data is stays encrypted at all times. Only when data is read is it decrypted and data written to disk files is encrypted before being sent to the disk.
Throughput to an encrypted volume will be somewhat slower than to a non-encrypted volume on an otherwise identical disk, but probably not so much as to be bothersome.
