Openssl speed test for Broadcom engine

Question

I'm using OpenSSL 1.0.1e.

The OpenSSL engine ubsec, requires additional library containing the actual implementation. The implementation library is /usr/lib/libvendor_ubsec.so.

To instruct from ubsec OpenSSL engine what implementation to load we use from code:

ENGINE_ctrl_cmd_string (&engine, "SO_PATH", vendor_ubsec, 0);

I want to run openssl speed test as following:

openssl speed rsa1024 -engine ubsec

But it fails, since openssl doesn't load libvendor_ubsec.so.

I understand that this related to OpenSSL dynamic engines and to load implementation I need to use something like:

openssl engine ubsec -pre SO_PATH:vendor_ubsec

My question how I "combine" two comamnd openssl speed and openssl engine to run speed test for ubsec engine>

Answer 1

Use the openssl command interpreter interactively instead of sending in single commands, that way, in the same execution context, you can load the engine and then run the commands. This site also has useful information on defining the library load paths
