+.Sh NAME
+.Nm activinit , cryptoinit , snkinit
+.Nd Modify or add user in ActivCard, CRYPTOCard, or SNK-004 authentication system.
+.Sh SYNOPSIS
+.Nm tokeninit
+.Op Fl f
+.Op Fl h
+.Op Fl m Ar mode
+.Op Fl s
+.Op Fl v
+.Ar user_ID
+.Op Ar user_ID ...
+.Sh DESCRIPTION
+.Pp
+The
+.Nm tokeninit
+utility may also be invoked by one of the names:
+.Nm activinit , cryptoinit ,
+or
+.Nm snkinit .
+Depending on the name it was invoked under, it will
+initialize the system information to allow one to use the
+ActivCard, CRYPTOCard or SNK-004 digital encryption token to login.
+The
+.Nm tokeninit
+utility is intended for use by the system administrator.
+.Pp
+Token cards system provides strong user authentication by combining a user's
+unique knowledge (a Personal Identification Number) and a physical object
+(the token) which the user must have in their possession to login.
+The system administrator programs the token with a secret encryption key 
+which is also stored in the database.  The user programs the token with
+a PIN.  To discourage exhaustive attempts to guess the PIN,
+configuration options permit the token to be programmed
+to erase knowledge of the shared secret should the user enter
+an excessive number of incorrect PIN entries.
+.Pp
+The user activates the token by entering their PIN into the token.
+After activating the token, the user enters a random number challenge
+presented by the host computer into the token.  The challenge is encrypted by
+the token and a response displayed.  The user then enters the 
+response at the host computer's prompt, where it is compared with the
+anticipated response.
+.Pp
+Token cards typically support multiple unique encryption keys.
+This facility allows a single token to be used for multiple computer
+systems, or multiple user instances on the same system.
+.Sh OPTIONS
+.Bl -hang
+.It Fl f
+Force reinitialization of an existing account.
+The current shared secret stored in the database will be replaced a new
+shared secret.
+The new shared secret must be entered into the token,
+replacing the current one.
+.It Fl h
+Read the shared secret as a 16 digit hexadecimal integer rather than
+a sequence of 8 octets.
+This is not supported when invoked as
+.Nm snkinit .
+.It Fl m
+Specify the input modes allowed for this user.  Possible modes are
+decimal (dec), hexadecimal (hex), phonebook (phone) and reduced-input (rim).
+Not all modes are available for all types of cards.  Multiple
+.Fl m
+options may be specified to enable multiple modes.
+By default only the hexadecimal mode is enabled, except for the SNK-004
+token, which by default only enables the decimal mode.
+If an attempt is made to initialize a card with only reduced-input, the
+default mode for the card is silently included.
+.It Fl s
+By default,
+.Nm tokeninit
+prompts for a shared secret to enter into the authentication database.
+The
+.Fl s 
+option generates a 64 bit cryptographically strong key for use in the token.
+This shared secret will be saved
+in the database for the user ID specified on the command line.
+After entering the shared secret into the token,
+determine that the checksum computed
+by the token matches the one displayed by
+.Nm tokeninit .
+.It Fl v
+Enable verbose mode.
+.Nm tokeninit
+will emit messages on the status of each user ID processed.
+.El
+.Sh REDUCED-INPUT MODE
+Reduced-input mode allows the token to predict the next challenge,
+given the current challenge.  This may be used to eliminate the need
+to enter the challenge to the token or may also be used with a paper list.
+Using a program such as
+.Xr x99token 1
+many challenges could be precomputed and printed.  This list should be
+kept secret.  This list can then take the place of an actual token until
+the system has issued all the challenges printed.
+Challenges are predicted by the following algorithm:
+.nf
+.sp
+* Encrypt the last challenge with the shared secret key
+
+* AND each byte of the response with 0x0f
+
+* Modulo each byte by 10 (0x0a)
+
+* ADD 0x30 (ASCII value of '0') to each byte
+.fi
+.sp
+The resulting 8 bytes are all ASCII decimal digits and are the next challenge.
+.Sh DIAGNOSTICS
+Diagnostic messages are logged via syslog(3) with the LOG_AUTH facility.
