| 9 | S/key \- A proceedure to use one time passwords for accessing computer systems. | |
| 10 | .SH DESCRIPTION | |
| 11 | .I S/key | |
| 12 | is a proceedure for using one time password to authenticate access to | |
| 13 | compter systems. It uses 64 bits of information transformed by the | |
| 14 | MD4 algorithm. The user supplies the 64 bits in the form of 6 English | |
| 15 | words that are generated by a secure computer. | |
| 16 | Example use of the S/key program | |
| 17 | .I key | |
| 18 | .sp | |
| 19 | Usage example: | |
| 20 | .sp 0 | |
| 21 | >key 99 th91334 | |
| 22 | .sp 0 | |
| 23 | Enter password: <your secret password is intered here> | |
| 24 | .sp 0 | |

| 29 | The programs that are part of the S/Key system are keyinit, key, and | |
| 30 | keyinfo. Keyinit is used to get your ID set up, key is | |
| 31 | used to get the one time password each time, | |
| 32 | keyinfo is used to extract information from the S/Key database. | |
| 33 | .sp | |
| 34 | When you run "keyinit" you inform the system of your | |
| 35 | secret password. Running "key" then generates the | |
| 36 | one-time passwords, and also requires your secret | |
| 37 | password. If however, you misspell your password | |
| 38 | while running "key", you will get a list of passwords | |
| 39 | that will not work, and no indication about the problem. | |
| 40 | .sp | |
| 41 | Password sequence numbers count backward from 99. If you | |
| 42 | don't know this, the syntax for "key" will be confusing. | |
| 43 | .sp | |
| 44 | You can enter the passwords using small letters, even | |
| 45 | though the "key" program gives them in caps. | |
| 46 | .sp | |
| 47 | Macintosh and a general purpose PC use | |
| 48 | are available. | |
| 49 | .sp | |
| 50 | Under FreeBSD, you can control, with /etc/skey.access, from which | |
| 51 | hosts and/or networks the use of S/Key passwords is obligated. | |
