OpenSC, engine_opensc and libp11 versions on github can use OpenSSL-1.0.2 with ECDSA.
They have the similar problems with memory leaks and ECDSA. But they do work,
if you can live with the memory leaks,for example to sign a certificate request
with ECDSA.

Any OpenSSL code to call PKCS#11 directly and eliminate the need for the engine_opensc
would welcome.
