NAME
     mkpasswd - generate new password, optionally apply it  to  a
     user

SYNOPSIS
     mkpasswd [ args ] [ user ]

INTRODUCTION
     mkpasswd generates passwords and can  apply  them  automati-
     cally  to users.  mkpasswd is based on the code from Chapter
     23 of the O'Reilly book "Exploring Expect".

USAGE
     With no arguments, mkpasswd returns a new password.

          mkpasswd

     With a user name, mkpasswd assigns a  new  password  to  the
     user.

          mkpasswd don

     The passwords are randomly generated according to the  flags
     below.


FLAGS
     The -l flag defines the length of the password.  The default
     is 9. The following example creates a 20 character password.

          mkpasswd -l 20

     The -d flag defines the minimum number of digits  that  must
     be  in the password.  The default is 2.  The following exam-
     ple creates a password with at least 3 digits.

          mkpasswd -d 3

     The -c flag defines the minimum number of  lowercase  alpha-
     betic  characters that must be in the password.  The default
     is 2.

     The -C flag defines the minimum number of  uppercase  alpha-
     betic  characters that must be in the password.  The default
     is 2.

     The -p flag  names  a  program  to  set  the  password.   By
     default,   /etc/yppasswd   is  used  if  present,  otherwise
     /bin/passwd is used.

     The -2 flag causes characters to  be  chosen  so  that  they
     alternate  between  right  and  left  hands  (qwerty-style),
     making  it  harder  for  anyone  watching  passwords   being
     entered.   This  can  also  make  it  easier for a password-
     guessing program.

     The -v flag causes the password-setting  interaction  to  be
     visible.  By default, it is suppressed.


EXAMPLE
     The following example creates a 15-character  password  that
     contains at least 3 digits and 5 uppercase characters.

          mkpasswd -l 15 -d 3 -C 5

     mkpasswd is in the public domain.  NIST and I would appreci-
     ate credit if this program or parts of it are used.
