I am comparing the size of OVF after exporting the VM using OVFtool, or others (doesn't make any difference). When I have no encryption, the VM exports with *2.91G size*.

If I try to export the same VM after encrypting the disk using dm-crypt, LUKS its sized at *4.34G*.

IIUC those formats are compressed for faster transfer. Encrypted data are in practice impossible to compress or to deduplicate. That's why you can see the size increase after you introduce encryption in VM.
