openssl: using a newly registered extension
When registering a new ASN.1 extension OBJ_create(), it should make it available for OBJ_ln2nid() and OBJ_sn2nid() searches that are performed in OpenSSL::X509::ExtensionFactory.create_ext
I've attached a ruby case where this should work,
As well as a C sample where you can see it working.
p.s. I wish that OBJ_txt2nid was added to the functions used when searching for the nid
