Thanks for that.  Apart from the standard keyUsage and use of an obsolete
certificatePolicies extension containing the usual Verisign policies and
qualifiers, the extension of interest is:
 
1157 30   32:  SEQUENCE {
1159 06    3:    OBJECT IDENTIFIER extKeyUsage (2 5 29 37)
1164 04   25:    OCTET STRING, encapsulates {
1166 30   23:        SEQUENCE {
1168 06    9:          OBJECT IDENTIFIER
            :            serverGatedCrypto (2 16 840 1 113730 4 1)
            :            (Netscape)
1179 06   10:          OBJECT IDENTIFIER
            :            serverGatedCrypto (1 3 6 1 4 1 311 10 3 3)
            :            (Microsoft enhanced key usage)
            :          }
            :        }
 
Interestingly, this enables SGC for both MSIE and Netscape in a single cert.
 
I don't have the necessary tools/software here to check this at the moment, but
is the signing cert - 'VeriSign International Server CA - Class 3' - available
from the browser?  It's not one of the standard ones included with MSIE or 
Netscape, unless it was in a version newer than the ones I examined.
 
Peter.
