The journal is encrypted unless you choose to put it on a separate non-encrypted device. In principle the data is encrypted into the journal, decrypted from the journal and then re-encrypted into its final location. In practice I've found that in file copying between disks, writing uses about twice as much cpu time as reading, so maybe the decryption from the journal can be avoided by caching.
