How do I perform a SHA512 hash in C++ WinRT?

Question

在C ++ WinRT中，C＃方法SHA512CryptoServiceProvider.ComputeHash（）的等价物是什么？

Answer 1

See Windows.Security.Cryptography.Core.CryptographicHash and friends. There is an example on that page demonstrating one usage, and the documentation for related classes and functions have examples as well.

For a "complete" example, you can take a look at the compute_sha1_hash function from my Boost-licensed CxxReflect library. It computes an SHA1 hash; computing an SHA512 hash should simply require changing the requested hash algorithm from "SHA1" to "SHA512". Note that this function is written using WRL, not C++/CX, though converting the code to C++/CX should be straightforward and would result in much more succinct code.
