CryFS (https://www.cryfs.org/) is a software that can be run by non-root
users that have access to /dev/fuse. Its command is directly used to
mount a directory ("/usr/bin/cryfs basedir mountpoint"), like command
"mount". Unmounting a mountpoint is done with "fusermount -u
mountpoint", /usr/bin/fusermount being a setuid-root program labeled
mount_exec_t.
EncFS (https://www.arg0.net/encfs) is a similar software that has been
considered insecure since a security audit in 2014 found vulnerabilities
that are not yet fixed (like https://github.com/vgough/encfs/issues/9).
gocryptfs (https://nuetzlich.net/gocryptfs/) is a similar software that
has been inspired by EncFS.
