+One of the nice things of S/Key is that it still leaves you the option
+to use regular UNIX passwords. In fact, the presence of S/Key support
+is completely invisible for a user until she has set up a password with
+the keyinit command. You can permit regular UNIX passwords for local
+logins, while at the same time insisting on S/Key passwords for logins
+from outside.
+
+ORIGIN
+
+These files are modified versions of the s/key files found on
+thumper.bellcore.com at 21 oct 1993. They have been fixed to
+run on top of SunOS 4.1.3 and Solaris 2.3.
+
+Installation is described at the end of this file.
+
+USAGE
+
+Use the keyinit command to set up a new series of s/key passwords.
+
+    wzv_6% keyinit
+    Updating wietse:
+    Old key: wz173500
+    Reminder - Only use this method if you are direct connected.
+    If you are using telnet or dial-in exit with no password and use keyinit -s.
+    Enter secret password: 
+    Again secret password: 
+
+    ID wietse s/key is 99 wz173501
+    BLAH BLA BLAH BLAH BLAH BLA
+
+Be sure to make your secret password sufficiently long. Try using a
+full sentence instead of just one single word.
+
+You will have to do a "keyinit" on every system that you want to login
+on using one-time passwords.
+
+Whenever you log into an s/key protected system you will see
+something like:
+
+    login: wietse
+    s/key 98 wz173501
+    Password:
+
+In this case you can either enter your regular UNIX password or
+your one-time s/key password. For example, I open a local window 
+to compute the password:
+
+    local% key 98 wz173501
+    Reminder - Do not use key while logged in via telnet or rlogin.
+    Enter secret password: 
+    BLAH BLA BLAH BLAH BLAH BLA
+
+The "BLAH BLA BLAH BLAH BLAH BLA" is the one-time s/key password.
+
+If you have to type the one-time password in by hand, it is convenient
+to have echo turned on so that you can correct typing errors. Just type
+a newline at the "Password:" prompt:
+
+    login: wietse
+    s/key 98 wz173501
+    Password: (turning echo on)
+    Password:BLAH BLA BLAH BLAH BLAH BLA
+
+The 98 in the challenge will be 97 the next time, and so on. You'll get
+a warning when you are about to run out of s/key passwords, so that you
+will have to run the keyinit command again.
+
+Sometimes it is more practical to carry a piece of paper with a small
+series of one-time passwords. You can generate the list with:
+
+    % key -n 10 98 wz173501
+    98: BLAH BLA BLAH BLAH BLAH BLA
+    97: ... 
+    96: ...
+
+Be careful when printing material like this!
+
+INSTALLATION
+
+To install, do: make sunos4 (or whatever), then: make install.  
+
+The UNIX password is always permitted with non-network logins.  By
+default, UNIX passwords are always permitted (the Bellcore code by
+default disallows UNIX passwords but I think that is too painful).  In
+order to permit UNIX passwords only with logins from specific networks,
+create a file /etc/skey.access. For example,
+
+    # First word says if UNIX passwords are to be permitted or denied.
+    # remainder of the rule is a networknumber and mask. A rule matches a
+    # host if any of its addresses satisfies:
+    # 
+    #	network = (address & mask)
+    # 
+    #what	network		mask
+    permit	131.155.210.0	255.255.255.0
+    deny	0.0.0.0		0.0.0.0
+
+This particular example will permit UNIX passwords with logins from any
+host on network 131.155.210, but will insist on one-time passwords in
+all other cases.

+.SH NAME
+S/key \-  A proceedure to use one time passwords for accessing computer systems.
+.SH DESCRIPTION
+.I S/key
+is a proceedure for using one time password to authenticate access to
+compter systems. It uses 64 bits of information transformed by the
+MD4 algorithm. The user supplies the 64 bits in the form of 6 English
+words that are generated by a secure computer.
+Example use of the S/key program 
+.I key
+.sp
+  Usage example:
+.sp 0
+ 	>key  99 th91334
+.sp 0
+ 	Enter password: <your secret password is intered here>
+.sp 0
+ 	OMEN US HORN OMIT BACK AHOY
+.sp 0
+ 	>
+.sp
+The programs that are part of the S/Key system are keyinit, key, and
+keyinfo. Keyinit is used to get your ID set up, key is
+used to get the one time password each time,
+keyinfo is used to extract information from the S/Key database.
+.sp
+When you run "keyinit" you inform the system of your
+secret password.  Running "key" then generates the
+one-time passwords, and also requires your secret
+password.  If however, you misspell your password
+while running "key", you will get a list of passwords
+that will not work, and no indication about the problem.
+.sp
+Password sequence numbers count backward from 99.  If you
+don't know this, the syntax for "key" will be confusing.
+.sp
+You can enter the passwords using small letters, even
+though the "key" program gives them in caps.
+.sp
+Macintosh and a general purpose PC use
+are available. 
+.sp
+Under FreeBSD, you can control, with /etc/skey.access, from which
+hosts and/or networks the use of S/Key passwords is obligated.

+.AT 3
+.SH NAME
+keyinit \-  Change password or add user to S/Key authentication system.
+.SH SYNOPSIS
+.B keyinit [\-s]   [<user ID >] 
+.SH DESCRIPTION
+.I keyinit
+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 UNIX password or using
+S/Key one-time passwords. 
+.PP
+When logging in from another machine you can avoid typing a real
+password over the network, by typing your S/Key pass phrase to the
+\fIkey\fR command on the local machine:  the program will respond with
+the one-time password that you should use to log into the remote
+machine.  This is most conveniently done with cut-and-paste operations
+using a mouse.  Alternatively, you can pre-compute one-time passwords
+using the \fIkey\fR command and carry them with you on a piece of paper.
+.PP
+\fIkeyinit\fR requires you to type your secret password, so it should
+be used only on a secure terminal. For example, on the console of a
+workstation. If you are using \fIkeyinit\fR while logged in over an
+untrusted network, follow the instructions given below with the \-s
+option.
+.SH OPTIONS
+.IP \-s
+Set secure mode where the user is expected to have used a secure
+machine to generate the first one time password.  Without the \-s the
+system will assume you are direct connected over secure communications
+and prompt you for your secret password.
+The \-s option also allows one to set the seed and count for complete
+control of the parameters.  You can use keyinit -s in compination with
+the 
+.I key
+command to set the seed and count if you do not like the defaults.
+To do this run keyinit in one window and put in your count and seed
+then run key in another window to generate the correct 6 english words
+for that count and seed. You can then
+"cut" and "paste" them or copy them into the keyinit window.
