eCryptfs is a cryptographic stacked Linux filesystem. eCryptfs stores
|
|
cryptographic metadata in the header of each file written, so that encrypted
|
|
files can be copied between hosts; the file will be decrypted with the proper
|
|
key in the Linux kernel keyring. There is no need to keep track of any
|
|
additional information aside from what is already in the encrypted file
|
|
itself. You may think of eCryptfs as a sort of "gnupgfs", or "gnupg as a
|
|
filesystem".
|
|
|
|
On Slackware, the Slackbuild script does not install the mount helper binaries
|
|
into /sbin, but to /usr/sbin. Because of this, using `mount -t ecryptfs` won't
|
|
work, and you must call the `[u]mount.ecryptfs*` binaries explicitly.
|
|
|
|
For an unprivileged user to use the `[u]mount.ecryptfs_private` executables,
|
|
it is necessary to set the suid bit on them, which the Slackbuild script also
|
|
does not do.
