lfsr_crypto's Issues

LFSR class

• checks in constructor

• more tests

• use dynamic_bitset or bitset if too slow

• operator()

• template specialization for right lfsr

• header only

• profile

Linear complexity check for lfsr class

• Chan-Games algorithm
• BK algorithm

Generator interface

comb_gen class

class comb_gen {
public:
    comb_gen(std::initializer_list<std::any> regs, 
                       std::function<size_t(std::vector<size_t)> func) : registers(regs), function(func) {}
    size_t operator()() {}
    std::string get_gamma(size_t steps);
    
private:
    std::vector<std::any> registers;
    std::vector<size_t> memory;
    std::function<size_t(const std::vector<size_t>&)> function; // can use both for register step and lin complexity computatuion;
};
