SHA512 C++ implementation

Implementation of a cryptographic hash function written in C++. SHA512 belongs to a SHA-2 family. It was designed by NSA and published in 2001.
Produced hash value is of size 512 bits.
Implementation is based on SHA-512 pseudocode.

SHA512 sum app

One can compile and use program to calcualte SHA512 sum:

g++ src/SHA512app.cpp src/SHA512.cpp -o sha512app

Two supported operations are:

• file hash with -f/-file option and file name
• string hash with -s/-string option and string

SHA512 in your C++ code

All you have to do to use this SHA512 implementation is:

• include header

#include "SHA512.h"

• create class object and use preferred method

SHA512 sha512;
sha512.hashString("string");
sha512.hashFile("fileName");

• compile your project with SHA512.cpp and link object files

g++ yourProgram.cpp SHA512.cpp -o yourProgram

Project's limitations

Because size() returns 64-bits value of type size_t only the hash of files and strings which sizes are not bigger than 64 bits can be calculated.
