The keygen utility has three purposes:

• Using the -c flag, to generate and store per-client 3DES/AES encryption keys, avoiding any DES weak keys.
• Using the -m flag, to generate and store a "master" HMAC SHA-1 key for WAN install, and to derive from the master key per-client HMAC SHA-1 hashing keys, in a manner described in RFC 3118, Appendix A.
• Using the -d flag along with either the -c or -m flag to indicate the key repository, to display a key of type specified by keytype, which must be one of 3des, aes, or sha1.

The net and cid arguments are used to identify a specific client. Both arguments are optional. If the cid option is not provided, the key being created or displayed will have a per-network scope. If the net option is not provided, then the key will have a global scope. Default net and code values are used to derive an HMAC SHA-1 key if the values are not provided by the user.

The following options are supported:

-c

Generate and store per-client 3DES/AES encryption keys, avoiding any DES weak keys. Also generates and stores per-client HMAC SHA-1 keys. Used in conjunction with -o.

-d

Display a key of type specified by keytype, which must be one of 3des, aes, or sha1. Use -d with -m or with -c and -o.

-m

Generate and store a "master" HMAC SHA-1 key for WAN install.

-o

Specifies the WANboot client and/or keytype.
