I verified that it does not seem to work, at least in the > obvious context. OSSL_PARAM_EC_ORDER is an unsigned integer (also a bignum) and it won't fit into int. So that's the reason why that call fails. Also the order is not a degree (maximum number of bits of a curve coordinate). -- Tomáš Mráz, OpenSSL
