You can retrieve a structure representing any supported extension using the function X509_get_ext_d2i. In the case of EKU you get back a STACK_OF(ASN1_OBJECT) which you can then examine. Have a look in the function x509v3_cache_extension in crypto/x509v3/v3_purp.c for an example. Steve. -- Dr Stephen N. Henson. OpenSSL project core developer.
