It seems like OpenSSL does not even attempt to use the engine for ciphers.

ENGINEs only work at the EVP level so your above command will just use the built in ciphers. If instead you do: openssl speed -evp aes-256-cbc It should work if you've set up an ENGINE to provide the default implementation. Steve. -- Dr Stephen N. Henson. OpenSSL project core developer.
