Just for info.
On my other debian servers running Jessie I have cryfs installed. And working correctly.
The version of cryfs is 0.9.7
Now, in Stretch, cryfs is a regular package but the version is 0.9.6
I tried to upgrade cryfs but without success.
I just hope cryfs will be very soon backported or the latest version (0.9.7) will become available on cryfs.org as a .deb package for Stretch
I also tried to compile from sources. But the binary is not working correctly.
