System-Glitch / SHA256

A C++ SHA256 implementation.

SHA256

A C++ SHA256 implementation.

Build

Minimum C++11.

Just run make all. There are no dependencies.

⚠️ DISCLAIMER

This library has been developed for research and learning purposes. It has not been audited for security nor compliance with the standard. It is not advised to use it in projects where security is important. Use wide-spread and reliable libraries such as OpenSSL instead.

Example usage

Sample program

Provide as many strings as you want. The program will hash all of them in order.

$ ./SHA256 "string" "string2"

As a library

#include "SHA256.h"

//...

string s = "hello world";
SHA256 sha;
sha.update(s);
std::array<uint8_t, 32> digest = sha.digest();

std::cout << SHA256::toString(digest) << std::endl;

Using tipi.build to install SHA256

SHA256 can be easily used with the tipi.build dependency manager, by adding the following to a .tipi/deps:

{
    "System-Glitch/SHA256": { }
}

An example to try is available in https://github.com/tipi-deps/example-System-Glitch-SHA256 (change the target name appropriately to linux or macos or windows):

tipi . -t <target>
