If you do a grep for 'Big Brother' or 'MiniTruth' on the entire notes
installation you will come up empty.
How I found the key data is as follows from my notes:
Set a breakpoint in SECGetKeyInfo() (it's in nnotes.dll).
This will be used to get either the recipients key, or the NSA's key.
(It seems to call SECGetKeyInfo to fetch the key info a few times).
ESI points to the name info.
When I ran it and displayed the string pointed to by ESI it showed:
O=MiniTruth CN=Big Brother
('MiniTruth' is from Orwell's 1984 -- the 'Ministry of Truth' (ie
government ministry of propaganda, lies, revisionism and unpublishing.)
I'll need to reinstall a few things to give you more data than that.
The notes version I used was a free demo / trial version reporting as:
46a (international) release 21 Nov 1997
downloaded from www.lotus.com. (you need to download domino if you
want to get it working -- notes alone I don't think will work without
a domino server -- domino includes a notes client, and domino server).
If I recall I think I figured the NSA's key was a 768 bit RSA key.
