What do you need the NID for? Maybe the code could be changed to use names instead of NIDs? The NIDs are somehow legacy thing that might eventually be completely internal at some point. However, if you need the NID, you should be able to use OBJ_sn2nid() to obtain the NID if the curve name is in t

Hi, How can I get the nid from the curve name for a EC key in OpenSSL 3? I'm porting code from OpenSSL 1.0.2. I'm converting this: ecc_curve_type = EC_GROUP_get_curve_name(EC_KEY_get0_group((const EC_KEY *)eckey)); if(ecc_curve_type == NID_undef) { to EVP_PKEY_get_utf8_string_
