Ah, I missed this. Works perfectly, thank you very much for the tip. I've also ported the engine to work on both OpenSSL 1.0 and 1.1 -- however the cast to a (mutable) EC_KEY_METHOD* isn't necessary for 1.1 (where the prototype accepts a const EC_KEY_METHOD*). However, when I want to set the sign function for v1.1, I want to override sig_sign, but use the OpenSSL default sign and sign_setup functions. For this, I use EC_KEY_METHOD_get_sign. Unfortunately, for no obvious reason, EC_KEY_METHOD_get_sign requires a EC_KEY_METHOD* instead of a const EC_KEY_METHOD*. Do you happen to know why this is? Looking at the code, there doesn't seem to be a reason for it. Gives an ugly compile-time warning.
