Hi,
Some questions about the microsoft certificate store:
- is there a way to extract (or export) certificates from a microsoft
certificate store when the certificates are marked as "not
exportable
- is there a way to extract the certificates from within a linux environment?
From a bit of research i did the other day, the private keys appear to
be stored at C:\Documents and Settings\<username>\Application
Data\Microsoft\Crypto\RSA for the user concerned. Further searches
seemed to indicate that they were secured with a user specific "master
key" derived from the machine's SID, the users name (or SID) and the
password used for that user's login.
I haven't researched this one any further, but I understand the same
mechanism is used for the EFS certificates (for obvious reasons) so
examination of http://www.lostpassword.com/efs.htm may yield some useful
clues.
