skeyinit — change password or add user to S/Key authentication system

skeyinit [-sxz] [-k passphrase] [-n count] [-p password] [-t hash] [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:

passphrase
Use pass phrase passphrase instead of asking for one to be entered.
count
Start the skey(1) sequence at count (default is 100).
password
Use password password instead of asking for one to be entered.
Allows the user to set the seed and count for complete control of the parameters. To do this run skeyinit in 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 the skeyinit window.
hash
Selects the hash algorithm to use. Available choices are md4 (the default), md5, or sha1.
Displays one-time password in hexadecimal instead of ASCII.
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.

skey(1), skeyaudit(1), skeyinfo(1)
