CVDES(8)

NAME
cvdes - convert DES encryption of loop devices

SYNOPSIS
cvdes file

DESCRIPTION
cvdes is used to convert DES-encrypted files or block devices used with loop devices from the encryption method used by version 0 to the one used by later versions of the loop device patches. The conversion is performed in-place. It is irreversible and must be done exactly once. Repeating it will make the data unusable.

WARNING
Attempts to convert with an invalid password are not detected and will scramble the data beyond recognition. cvdes is completely untested.
