Running the WEP wfkseed Command

The

wfkseed command creates the seed that enables you to generate random

numbers. You run this command twice to create seeds for the NPK and the LTSSs.

To create the LTSS seed:

1. At the C shell prompt, enter

wfkseed

WEP asks

Do you wish to create the LTSS or NPK Key File? [LTSS]:

2. Press Return to create the LTSS key ﬁle.

WEP displays this message:

To initialize the seed for the cryptographic random number generator,

please now enter a series of characters which you would consider to

be 'random.' As you enter them, dots '.' will be displayed to

indicate progress. If your string is not 'random' enough, questions

'?' will be displayed. In that case, modify the pattern you are

entering. When enough data is input, you will be prompted to stop

(near 3 lines of input)...

3. Type a series of random characters.

The screen displays a dot for each 5 keystrokes that WEP accepts.

... .... .... .... ....

.... .... .... .... ....

.... .... .... ..

If your keystrokes are not random enough, the screen displays ???

After you enter a sufﬁcient number of random keystrokes, WEP displays a

completion message, and returns you to the prompt.

All done, thank you!

4. Enter the wfkseed command again to generate the NPK key ﬁle.

WEP asks

Do you wish to create the LTSS or NPK Key File? [LTSS]:

5. Type NPK and press Return.

6. Repeat Step 3 to generate the NPK key ﬁle.
