Since the demise(?) of TrueCrypt I have been using the "built in" encryption features of Linux (dm-crypt, cryptsetup, luks) in a number of ways. On my servers I have fill disk encryption of data drives which I automagically decrypt on bootup with /etc/crypttab and a key file. Prior to this I decrypted and mounted the drives as needed with scripts. I also have removable media such as flash drives and USB connected external hard drives which are also encrypted. Mate (and Gnome before it) will prompt me for the passphrase upon connecting such a device and then, provided I provide the correct passphrase, mount the device as if by magic. This leaves one situation which TrueCrypt handled seamlessly and which I have not found a convenient "native" procedure.

In TrueCrypt I created a container/file sized to fit on a DVD. I would open and mount the container with Truecrypt, copy data to it, close it and then write the file to DVD. Worked great. I can do the same thing with cryptsetup/luks/mount etc. but the process is a bit tedious. I guess I could enhance my existing scripts to make them more general purpose and interactive. However...

Am I overlooking something in Mate/Gnome which can decrypt and mount an encrypted file/volume interactively in a similar way to the way encrypted removable media is handled?

TIA,

Have you tried Veracrypt?

Thanks agillator,

Yes, I have used Veracrypt. I used to use Truecrypt until it came to an abrupt end - whatever happened. I followed the development of the successors - Veracrypt, Cyphershed and I think there were a couple of others for a while. I decided to stick with the native capability within Linux. Unfortunately Veracrypt will not open "container" files created with cryptsetup/luks. That sort of interface/functionality is what I was spoiled with in Truecrypt.
