[imp] S/MIME importing private keys

[Reuben Farrelly]

Hi,

I've spent the best part of the evening trying to figure out how to 
import my personal digital certificate into my profile in Imp, but 
had no joy.  I am using -CVS, and I am all synced and up to date with 
the repository.

I've ticked the box for S/MIME support, and certainly mails that come 
in are being checked and marked as signed, and have read the help 
files all around the S/MIME area.  I can also add certificates to the 
address book for users (there is a link for "Import public key" in 
the S/MIME options).  However there is no option at all to add my own 
private certificates.  I was expecting this to be near "Your S/MIME 
Public/Private Certificates" - and logically thought it would be a 
separate option to the public certificates.

If I create a new mail and tick the option of signing it, I get asked 
for a passphrase, but no passphrase I have tried actually is 
accepted.  I've tried importing all manner of keys into the public 
store but to no avail..

What am I missing here?
