Here is question,can you help me out? Thanks.
   I am working to write an openssl engine to use cryptographic algorithm in a hardware device. The hardware device support asymmetric/symmetric algorithm, for example:rsa/aes.
  When I write openssl engine, I shall use ENGINE_load_private_key() function to load and use asymmetric private key in the hardware device.
  How to set and use symmetric key in the hardware device ? is there any example for my case?
