mount.ecryptfs_private(1)	   eCryptfs	     mount.ecryptfs_private(1)

NAME
       mount.ecryptfs_private - eCryptfs private mount helper.

SYNOPSIS
       mount.ecryptfs_private

       NOTE:  This  program  will not dynamically load the relevant keys.  For
       this reason, it is recommended that users use ecryptfs-mount-private(1)
       instead!

DESCRIPTION
       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.

       If, and only if:
	 - the private mount passphrase is in their kernel keyring, and
	 - the current user owns both ~/.Private and ~/Private, and
	 - ~/Private is not already mounted, then

       This program will:
	 - mount ~/.Private onto ~/Private
	 - 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).

       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).

FILES
       ~/.Private - underlying directory containing encrypted data

       ~/Private - mountpoint containing decrypted data (when mounted)

       ~/.ecryptfs/Private.sig	-  file	 containing  signature	of  mountpoint
       passphrase

       ~/.ecryptfs/wrapped-passphrase  -  mount passphrase, encrypted with the
       login passphrase
