Yes.

The easiest is to install a distribution which already includes
support for those hashes "out of the box".  You can try ours:

Or one from ALT Linux team:

Alternatively, you may "patch" the support into whatever distribution
you have, using these packages:

	http://www.openwall.com/crypt/
	http://www.openwall.com/tcb/

Finally, we may do this work for you if it's paid for. ;-)
