skeyinit —
change password or add user to S/Key authentication system
  
    | skeyinit | [ -sxz] [-kpassphrase] [-ncount] [-ppassword] [-thash] [user] | 
skeyinit initializes the system so you can use S/Key
  one-time passwords to login. The program will ask you to enter a secret pass
  phrase; enter a phrase of several words in response. After the S/Key database
  has been updated you can login using either your regular password or using
  S/Key one-time passwords.
skeyinit requires you to type a secret
    password, so it should be used only on a secure terminal.
The following options are available:
  - -kpassphrase
- Use pass phrase passphrase instead of asking for one
      to be entered.
- -ncount
- Start the skey(1) sequence at
      count (default is 100).
- -ppassword
- Use password password instead of asking for one to
      be entered.
- -s
- Allows the user to set the seed and count for complete control of the
      parameters. To do this run skeyinitin one window
      and put in your count and seed; then run
      skey(1) in another window to
      generate the correct 6 english words for that count and seed. You can then
      “cut-and-paste” or type the words into theskeyinitwindow.
- -thash
- Selects the hash algorithm to use. Available choices are md4 (the
      default), md5, or sha1.
- -x
- Displays one-time password in hexadecimal instead of ASCII.
- -z
- Allows the user to zero their S/Key entry.
- user
- The username to be changed/added. By default the current user is operated
      on, only root may change other user's entries.
  - /etc/skeykeys
- database of information for the S/Key system.
