About Crypto Engine sample code
===============================
af_alg:
Sample code which using socket's AF_ALG API to process data encryption and decryption.
AF_ALG API is the user space interface to kernel's crypto subsystem.
kcapi:
Sample code which using libkcapi's API to process data encryption and decryption.
libkcapi is a library which base on AF_ALG but providing more convenience interface for user.
openssl:
Sample code which using OpenSSL's API to process data encryption and decryption.
OpenSSL hardware engine for AIC SOC is base on libkcapi.
