       ftpasswd  is a Perl script which can be used to manipulate the password
       and group files suitable for use with ProFTPD  AuthUserFile  and  Auth
       GroupFile  configuration  directives.   The idea is somewhat similar to
       Apaches htpasswd program.

       Required options are  --passwd,	--group,  or  --hash.	These  specify
       whether	ftpasswd  is  to  operate  on  a  passwd(5)  format file, on a
       group(5) format file, or simply to generate a  password	hash,  respec

       If used with --passwd, ftpasswd creates a file in the passwd(5) format,
       suitable for use with proftpds AuthUserFile  configuration  directive.
       You will be prompted for the password to use of the user, which will be
       encrypted, and written out as the encrypted string.  By default,  using
       --passwd will write output to "./ftpd.passwd",

       If  used with --hash, ftpasswd generates a hash of a password, as would
       appear in an AuthUserFile.  The hash is written to standard out.   This
       hash is suitable for use with proftpds UserPassword directive.

       If  used  with --group, ftpasswd creates a file in the group(5) format,
       suitable for use with proftpds AuthGroupFile configuration  directive.
       By default, using --group will write output to "./ftpd.group".

       -F, --force
	      If  the password or group file be used already exists, delete it
	      and write a new one.

	      Write output to specified file (password or group files), rather
	      than default one.

	      Descriptive  string  for the given user (usually the users full

	      Set primary group ID for this user (optional,  will  default  to
	      given --uid value if absent) when  --passwd is specified.

	      numerical group ID.

       -h, --help, --version
	      Show usage and version of the program.

	      Set the home directory for the user (required).

       --des, --md5
	      Use the DES or MD5 algorithm for encrypting passwords.  The lat
	      ter is the default.

       --name=username, --name=groupname
	      Name of the user account or group (required).  If the name  does
	      not exist in the specified output-file, an entry will be created
	      for it. Otherwise, the given fields will be updated.

	      Shell for the user (required).  Recommended: /bin/false

	      Update only the password field for a user.  This option requires
	      that  the  --name option be used, but no others.	This also dou
	      ble-checks the given password against the users  current	pass
	      word  in the existing passwd file, and requests that a new pass
	      word be given if the entered password is the same as the current

	      Double-checks the given password against the system password for
	      the user, and requests that a  new  password  be	given  if  the
	      entered password is the same as the system password.  This helps
	      to enforce different passwords for different types of access.

	      Read the password directly from standard in rather than  prompt
	      ing  for	it.   This is useful for writing scripts that automate
	      use of ftpasswd.

	      Causes ftpasswd to use Alec Muffets cracklib routines in	order
	      to  determine and prevent the use of bad or weak passwords.  The
	      optional path to this option specifies the path to  the  dictio
	      nary  files  to  use  -- default path is /usr/lib/cracklib_dict.
	      This requires the Perl Crypt::Cracklib module to be installed on
	      your system.

	      Prompt  for  a  group password.  This is disabled by default, as
	      group passwords are not usually a good idea at all.

       -m username, --member=username
	      user to be a member of the group.  This  argument  may  be  used
	      This  argument  may  be  used multiple times to specify the full
	      list of users to be members of this group.

       No known bugs at this time.  If you discover any bugs,  please  contact
       the author.
