KeccakCryptoRng class
KeccakCryptoRng - A KeccakF1600 based cryptographic quality pseudo-random number generator. The quality of the generated pseudo random numbers is comaparable to the hash output of SHAKE128.
Base classes
- class KeccakRng
Public types
- using result_type = uint64_t
- Integral type of the KeccakRng generator results.
Constructors, destructors, conversion operators
- KeccakCryptoRng() explicit
- Initialize and seed the generator from a system specific nondeterministic random source.
-
template <class SeedSeq>KeccakCryptoRng(SeedSeq& seed_sequence) explicit
- Initialize and seed the generator from seed_sequence.
Public functions
- void auto_seed()
- Seed the generator from a system specific nondeterministic random source.
- auto bit_capacity() const → size_t
- Amount of bits used to store hidden random number generator state.
- void discard(unsigned long long count)
- void forget()
-
template <typename RandomAccessIterator>void generate(RandomAccessIterator begin, RandomAccessIterator end)
- Fill the range [begin, end) with random unsigned integer values.
-
