Examples of adding Private Enterprise Numbers (PEN's) Extensions to CSR

[Philip Prindeville]

Hi,

I need to generate CSR's with some Extensions included that use our PEN's as 
allocated by IANA.

Are there any examples of this?

Also, I'm looking at X509_REQ_add_extensions_nid() and it takes a 
STACK_OF(X509_EXTENSION) but it doesn't seem to actually iterate through the 
stack...  Is this code even correct?  What am I missing?  Ditto for 
X509_REQ_add_extensions().

Thanks,

-Philip
