SYNOPSIS

       encfsctl [command command_args]

       encfsctl rootdir

       encfsctl info rootdir

       encfsctl passwd rootdir

       encfsctl showcruft rootdir

       encfsctl decode [--extpass=prog] rootdir [encoded name ...]

       encfsctl encode [--extpass=prog] rootdir [plaintext name ...]

DESCRIPTION

       encfsctl is an administrative tool for working with EncFS filesystems.
       It is capable of changing the user supplied password, displaying basic
       information about an encrypted volume, and other related operations.

COMMANDS

       info
           Display basic information about the filesystem.  Takes a single
           argument, rootdir, which is the root directory of the encrypted
           filesystem.  The filesystem need not be mounted.  Info is also the
           default command if only a root directory is provided on the command
           line.

       passwd
           Allows changing the password of the encrypted filesystem.  The user
           will be prompted for the existing password and the new password.

       showcruft
           Recursively search through the entire volume and display all files
           which are not decodable (only checks filename encoding, not block
           MAC headers).  This might be useful for cleanup in case you’ve made
           use of features which create files which are not decodable under
           the primary key.

       decode
           Allows you to specify an encoded name on the command line, and
           displays decoded version.  This is mostly useful for debugging, as
           debug messages always display encrypted filenames (to avoid leaking
           sensitive data through the debug channels).  So this command
           provides a way to decode the filenames.

           The --extpass option can be used to specify the program which
           returns the password - just like with encfs.

           If no names are specified on the command line, then a list of
           filenames will be read from stdin and decoded.

       encode
           Allows you to specify a filename on the command line, and displays
           its encoded version. This is useful if e.g. you are taking a backup
           of an encrypted directory and would like to exclude some files.

           The --extpass option can be used to specify the program which
           returns the password - just like with encfs.

           If no names are specified on the command line, then a list of
           filenames will be read from stdin and encoded.

EXAMPLES

       Show information about an encrypted filesystem:

        % encfsctl info ~/.crypt

        Version 5 configuration; created by EncFS 1.1 (revision 20040504)
        Filesystem cipher: "ssl/aes" , version 2:1:1
        Filename encoding: "nameio/block" , version 3:0:1
        Key Size: 192 bits
        Block Size: 512 bytes
        Each file contains 8 byte header with unique IV data.
        Filesname encoded using IV chaining mode.
