ecryptfs-setup-private(1)


NAME

   ecryptfs-setup-private - setup an eCryptfs private directory.

SYNOPSIS

   ecryptfs-setup-private  [-f|--force]  [-w|--wrapping]  [-b|--bootstrap]
   [-n|--no-fnek]  [--nopwcheck]  [-u|--username   USER]   [-l|--loginpass
   LOGINPASS] [-m|--mountpass MOUNTPASS]

OPTIONS

   Options available for the ecryptfs-setup-private command:

   -f, --force
          Force overwriting of an existing setup

   -w, --wrapping
          Use an independent wrapping passphrase, different from the login
          passphrase

   -u, --username USER
          User to setup, default is current user if omitted

   -l, --loginpass LOGINPASS
          System  passphrase  for  USER,  used  to  wrap  MOUNTPASS,  will
          interactively prompt if omitted

   -m, --mountpass MOUNTPASS
          Passphrase  for  mounting  the ecryptfs directory, default is 16
          bytes from /dev/random if omitted

   -b, --bootstrap
          Bootstrap a new user's entire home directory

   --undo Display instructions on how to undo an encrypted private setup

   -n, --no-fnek
          Do not encrypt filenames; otherwise, filenames will be encrypted
          on systems which support filename encryption

   --nopwcheck
          Do  not  check  the  validity  of  the  specified login password
          (useful for LDAP user accounts)

   --noautomount
          Setup this user such that the encrypted private directory is not
          automatically mounted on login

   --noautoumount
          Setup this user such that the encrypted private directory is not
          automatically unmounted at logout

DESCRIPTION

   ecryptfs-setup-private  is  a  program   that   sets   up   a   private
   cryptographic mountpoint for a non-root user.

   Be  sure  to  properly escape your parameters according to your shell's
   special character nuances, and also surround the parameters  by  double
   quotes, if necessary. Any of the parameters may be:

     1) exported as environment variables
     2) specified on the command line
     3) left empty and interactively prompted

   The  user  SHOULD ABSOLUTELY RECORD THE MOUNT PASSPHRASE AND STORE IN A
   SAFE LOCATION.  If the mount passphase  file  is  lost,  or  the  mount
   passphrase is forgotten, THERE IS NO WAY TO RECOVER THE ENCRYPTED DATA.

   Using  the  values  of  USER, MOUNTPASS, and LOGINPASS, ecryptfs-setup-
   private will:
     - Create ~/.Private (permission 700)
     - Create ~/Private (permission 500)
     - Backup any existing wrapped passphrases
     - Use LOGINPASS to wrap and encrypt MOUNTPASS
     - Write to ~/.ecryptfs/wrapped-passphrase
     - Add the passphrase to the current keyring
     - Write the passphrase signature to ~/.ecryptfs/Private.sig
     - Test the cryptographic mount with a few reads and writes

   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

   ~/.ecryptfs/auto-mount

   ~/.Private - underlying directory containing encrypted data

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

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

   ~/.ecryptfs/Private.mnt - file containing path of the private directory
   mountpoint

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

   ~/.ecryptfs/wrapping-independent - this file  exists  if  the  wrapping
   passphrase is independent from login passphrase
