\fBmount.ecryptfs_private\fP is a mount helper utility for non-root users to cryptographically mount a private directory, ~/Private.
12
- the private mount passphrase is in their kernel keyring, and
13
- the current user owns both ~/.Private and ~/Private, and
14
- ~/Private is not already mounted, then
17
- mount ~/.Private onto ~/Private
18
- as an ecryptfs filesystem
19
- using the AES cipher
20
- with a key length of 16 bytes
21
- using the passphrase whose signature is in ~/.ecryptfs/Private.sig
23
The only setuid operation in this program is the call to \fBmount\fP(8).
25
The \fBecryptfs-setup-private\fP(1) utility will create the ~/.Private and ~/Private directories, generate a mount passphrase, wrap the passphrase, and write the ~/.ecryptfs/Private.sig.
27
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 \fBpam_ecryptfs\fP(8).

\fI~/.Private\fP - underlying directory containing encrypted data
32
\fI~/Private\fP - mountpoint containing decrypted data (when mounted)
34
\fI~/.ecryptfs/Private.sig\fP - file containing signature of mountpoint passphrase
36
\fI~/.ecryptfs/wrapped-passphrase\fP - mount passphrase, encrypted with the login passphrase
