With all the info on protecting passwords and data lately, I haven’t seen any mention of encrypted containers. Containers create a virtual encrypted disk within a file that mounts as a real disk.
I don’t consider myself an advanced user, but I’m a fan of VeraCrypt (spinoff of TrueCrypt) and maintain three different encrypted containers.
Containers can be created with multiple encryption methods such as AES-256 and Twofish. Very long passwords of gibberish work fine.
You can make a double container with one encrypted container hidden inside another container. Containers are not “opened”, they are mounted as a real disk similar to image backups.
You can copy encrypted containers you create on a local drive into the cloud for storage. They are seen as a single unidentified object, not a file in the usual sense.
Does anyone use encrypted containers?
