Creating Seeds on a PC

To use a PC to create seeds that the WEP software uses to generate NPKs and

LTSSs, issue the

wfkseed command at the DOS prompt. Default values exist for

the key ﬁle path and the length of the LTSS key. If you want to change these

values, do so before you create the seeds.

Changing the Path to the Key Files

WF_KEY_FILE_PATH is an environment variable that resides in the

\windows\siteman.ini ﬁle. It deﬁnes the location, or directory path, for WEP to

write the seeds, and from which Site Manager can both retrieve the seeds, and

write the generated keys to LTSS and NPK ﬁles. The default value of the path is

n:, where n is removable media.

If you want to change the storage place for your key ﬁles, use an editor such as

Notepad to edit the WF_KEY_FILE_PATH line.

Changing the Length of the LTSS Key Generator

You can set the length of the LTSSs to a value other than the default of 128 bits by

editing the WF_LTSS_KEY_GEN_LEN line in the \windows\siteman.ini ﬁle. Use

an editor such as Notepad. You can enter a value from 128 to 248.

Running the

wfkseed Command

The

wfkseed command creates the seed that enables WEP to generate random

numbers. You run this command twice to create seeds for both the NPKs and the

LTSSs.

1. At the DOS prompt, enter

wfkseed

WEP asks

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

Note: Store the ﬁles containing NPKs and LTSSs on removable media, such

as ﬂoppy disks, and store that media in a safe place.
