Own HW Supported RSA provider

[tomasz bartczak]

Hi,
I want to implement my own provider that enables RSA encryption using a HW 
chip. OpenSSL already comes with default provider that provides RSA 
implementation. Could you please explain to me how to add my own provider and 
make sure it is selected over the one from default provider and still have 
access to other algorithms that come with the default provider.
Thanks
Tom
