Hi Steve, Thanks, that certainly corrected it. I guess I'm perplexed as to why using
ecgroup = EC_GROUP_new_by_curve_name(NID_X9_62_prime256v1); would not automatically set that flag since I'm explicitly giving the curve name already? Thanks, Erik ....................................

When you generate the key try calling: EC_GROUP_set_asn1_flag(group, OPENSSL_EC_NAMED_CURVE); Steve. -- Dr Stephen N. Henson. OpenSSL project core developer.
