TinySHA1

A simple header only SHA1 implementation in C++ (no dependencies). Based on the implementation in boost::uuid::details.

SHA1 Wikipedia Page: http://en.wikipedia.org/wiki/SHA-1

Usage

Just include the header file to use in your code. There are no dependencies other than standard C++.

#include "TinySHA1.hpp"

void testSHA1(const std::string& val) {
  sha1::SHA1 s;
	s.processBytes(val.c_str(), val.size());
	uint32_t digest[5];
	s.getDigest(digest);	
	char tmp[48];
	snprintf(tmp, 45, "%08x %08x %08x %08x %08x", digest[0], digest[1], digest[2], digest[3], digest[4]);
	std::cout<<"Calculated : (\""<<val<<"\") = "<<tmp<<std::endl;
}
