Sir:

    I am working with Intel Haswell Architecture. May someone please tell me where to find such information?

Any suggestion I would appreciate.

Hi Joe,
       I assume you meant Intel SHA extensions? If so, you can refer to it at:  https://software.intel.com/en-us/isa-extensions/intel-sha

        Till now, I still cannot find its real usage and purpose.

Hi Joe,
Your question really should be posted in the Intel ISA Extentions Forum Suport who can answer in more detail. The forum link is: https://software.intel.com/en-us/forums/intel-isa-extensions 
It's primarily used in cryptographic applications in addition to data integrity, message authentication, and digital signatures applications as well. Please post any further questions you may have in the above Intel ISA  Extensions forum for more info, appreciate much.
