When key management is registering with OpenSSL and Sign&Verify registering with qatprovider, why both are offloading to OpenSSL?

[bjayanax]

When we registered keymgmt and sign&verify with qatprovider both are offloading to qatprovider. If we are using keymgmt from OpenSSL and sign&verify from qatprovider both are offloading to OpenSSL. May I know reason for this behaviour?

Do we need to use both keymgmt and sign&verify from same library?

Note: Checked few algorithms(RSA, ECDSA & SM2) and Observed this behavior

What do you mean by "registering" here? You'll have to describe the application calls and configuration for us to help. Of course to be able to move keys among providers all of them has to have implemented a keymgmt (at least partially).
