    SHA 512 hash in C++

    I'm creating a simple hashing program and wish to use the SHA hash in
    it. I was wondering if there was an easy way to do that. In Ruby you
    can just say:
    require "Digest"
    sha_hex = Digest::SHA512. hexdigest("some string")
    print sha_hex

    Is there a comparable way to do this in c++? I would like to have the
    speed it offers instead of having to wait for ruby.

    Thanks!

      You will probably need a third-party library like OpenSSL. If you're on
      a Unix-like platform, such a library should already be installed; try
      "man crypto". OpenSSL is written in C, but Google also turns up various
      C++ implementations , including wrappers around OpenSSL.

          "man crypto". OpenSSL is written in C, but Google also turns up various
          Interesting. I looked up Crypto++ and it was quite interesting, but I
          seem to be having trouble with some of the how-to. There is a
          CalculateDigest method for SHA512, but I seem to be over my head in C+
          + syntax. Any more help?
          Thanks,

              Can you post a complete program that won't compile for you, or isn't
              doing what you expect?
