mount.ecryptfs_private - eCryptfs private mount helper.
NOTE: This program will not dynamically load the relevant keys. For
this reason, it is recommended that users use ecryptfs-mount-private(1)
mount.ecryptfs_private is a mount helper utility for non-root users,
who are members of ecryptfs group, to cryptographically mount a private
directory, ~/Private by default.
This program optionally takes one argument, ALIAS. If ALIAS is
omitted, the program will default to using "Private" using:
- $HOME/.Private as the SOURCE
- $HOME/Private as the DESTINATION
- $HOME/.ecryptfs/Private.sig for the key signatures.
If ALIAS is specified, then the program will look for an fstab(5) style
- $HOME/.ecryptfs/ALIAS.conf and for key signature(s) in:
The mounting will proceed if, and only if:
- the required passphrase is in their kernel keyring, and
- the current user owns both the SOURCE and DESTINATION mount points
- the DESTINATION is not already mounted
This program will:
- mount SOURCE onto DESTINATION
- as an ecryptfs filesystem
- using the AES cipher
- with a key length of 16 bytes
- using the passphrase whose signature is in ~/.ecryptfs/Private.sig
The only setuid operation in this program is the call to mount(8) or
The ecryptfs-setup-private(1) utility will create the ~/.Private and
~/Private directories, generate a mount passphrase, wrap the
passphrase, and write the ~/.ecryptfs/Private.sig.
The system administrator can add the pam_ecryptfs.so module to the PAM
stack which will automatically use the login passphrase to unwrap the
mount passphrase, add the passphrase to the user's kernel keyring, and
automatically perform the mount. See pam_ecryptfs(8).
~/.Private - underlying directory containing encrypted data
~/Private - mountpoint containing decrypted data (when mounted)
~/.ecryptfs/Private.sig - file containing signature of mountpoint
~/.ecryptfs/wrapped-passphrase - mount passphrase, encrypted with the
ecryptfs(7), ecryptfs-rewrap-passphrase(1), ecryptfs-setup-private(1),
keyctl(1), mount(8), umount.ecryptfs_private(1), pam_ecryptfs(8),
