CNAME(8)		     System Manager's Manual			CNAME(8)

NAME
     cname

SYNOPSIS
     cname [ -3bms ] [ -v ]

DESCRIPTION
     cname  prompts  for  a passphrase and reads, from standard input, a list of
     CFS encrypted file names (e.g., "51051f97e31613b7").  It produces, on stan-
     dard output, a corresponding list of cleartext names.   By  default,  names
     are  decrypted  using standard 2-key hybrid mode single-DES.  The -3 option
     specifies 2-key hybrid mode triple DES.  -m specifies 1-key hybrid  MacGuf-
     fin. -s specifies SAFER-SK128.  The -v option includes the ciphertext names
     in the output.

     All  names  must be specified one per input line, as individual path compo-
     nents (full path names are not accepted).	If a name cannot be decrypted to
     printable characters, "???" is printed in its place.  This is the only  way
     to detect an incorrect passphrase.

     cname  is intended to assist in making sense of CFS directories when no CFS
     daemon is available.  It is also useful in locating files from backups.

BUGS
     Does not work with new format (1.3 and later) directories.

     The program is easily confused by slightly wrong input.  It would be better
     if it could transparently translate the output from other programs such  as
     ls(1), tar(1) and dump(8).
