FrozenStorm is a project to make cryptography, hashing, checksumming, compression and transformation algorithms available over a unified interface.
FrozenStorm has a simple an unified C interface for its various components. This is how you generate a SHA1 hash and print it to the console in C:
#include <stdio.h>
#include "FrozenStorm.h"
void sha1example()
{
const char* data = "sha1";
unsigned char* hash;
size_t hashsize, i;
hash_sha1(data, strlen(data), &hash, &hashsize);
for (i = 0; i < hashsize; i++)
printf("%02x", hash[i]);
puts("");
frozen_free(hash);
}If you use the provided C++ wrapper it looks like this:
#include <stdio.h>
#include "FrozenStormWrapper.h"
void sha1example()
{
auto data = "sha1";
auto hash = FrozenStorm::hash_sha1(data, strlen(data));
puts(FrozenStorm::hash_ToString(hash).c_str());
}
