ODP: dynamic engine load

[Piotr Lobacz]

Btw i have verified that in openssl command line tool if i switch order from the one that worked for me:

OpenSSL> engine dynamic -pre SO_PATH:/usr/lib/engines-1.1/libpkcs11.so -pre ID:pkcs11 -pre LIST_ADD:1 -pre LOAD -pre MODULE_PATH:/usr/lib/libckteec.so

to the one that was in the code:

OpenSSL> engine dynamic -pre SO_PATH:/usr/lib/engines-1.1/libpkcs11.so -pre MODULE_PATH:/usr/lib/libckteec.so -pre ID:pkcs11 -pre LIST_ADD:1 -pre LOAD

the error is the same as for me in the C# code. So the question is if you are telling me that the proper order is like that:

dynamic --> set SO_PATH --> LOAD and then set all parameters of
the engine that SO_PATH implements.

does the order which i used is also correct one?

At this point you should do the "LOAD" control to get the dynamic
engine shell replaced by pkcs11. Then set the ID and the MODULE_PATH.

So its dynamic --> set SO_PATH --> LOAD and then set all parameters of
the engine that SO_PATH implements.
