generator.h: add both string and cstring ..since we depend on both 2021-10-24 22:04:14 +02:00			`#include <string>`
			`#include <cstring>`
switch to using {tuples,128bit int for ctr} multiple changes combined in a single commit, I know... also, a move towards the use of OOP paradigm is imminent as we now have to do rewrites at multiple places in the code for any minor change 2021-10-26 15:59:22 +02:00			`#include <tuple>`

chore: use int64_t instead of long 2021-10-30 21:02:03 +02:00			`std::string do_crypto(int64_t k, unsigned __int128 ctr);`
add do_crypto declaration 2021-10-24 22:11:29 +02:00
add reseed() and do_sha() functions currently the bodies of the functions are pretty much bogus 2021-10-30 21:06:54 +02:00			`std::tuple<G_state, unsigned __int128> reseed(G_state G, const std::string& s);`

			`int64_t do_sha(int64_t key_with_seed);`
