Subject: [EXTERNAL] [MS-GKDI] GetKey — Group Keys and Seed Keys

Hi dochelp,

The documentation for GetKey ([MS-GKDI] 3.1.4.1) states that, in general, there are \
four types of GetKey request: two requesting the latest group key, and two requesting \
a specific seed key. If L0KeyID, L1KeyID, and L2KeyID are all equal to −1, the caller \
has requested a group key, and if they are all greater than −1, a seed key.

Further on, the documentation states:

“6. If the client is only authorized to access public keys […] compute the public key \
corresponding to the SK […] Return the result in the ppbOut parameter of the GetKey \
method […] and then exit. “7. If the client is authorized to access seed keys […] \
then:  [directions follow for returning a seed key].”

Steps 6 and 7, taken literally, seem to imply that whether to return a seed key \
depends only on the client’s access privileges. But that would be contrary to the \
earlier passage which leaves the choice up to the client — although still restricted \
by their privileges.

Which reading is the correct one?

Regards,
Joseph
