This application consists of three sections:
  1. Initialize the Intel IPP Cryptography library. The Intel IPP Cryptography library is auto-initialized with the first call of an Intel IPP Cryptography function.
    In certain debugging scenarios, it is helpful to force a specific implementation layer using
    ippcpSetCpuFeatures()
    , instead of the best as chosen by the dispatcher.
  2. Get the library layer name and version. You can also get the version information using the
    ippcpversion.h
     file located in the
    /include
     directory.
  3. Show the hardware optimizations used by the selected library layer and supported by CPU.
