RandomNumberGenerator
abstract class RandomNumberGenerator;
This class represents a random number (RNG) generator object.
static RandomNumberGenerator makeRng();
Create a seeded and active RNG object for general application use Added in 1.8.0
static RandomNumberGenerator makeRng(AlgorithmFactory af);
Create a seeded and active RNG object for general application use Added in 1.11.5
abstract void randomize(ubyte* output, size_t length);
- Parameters
ubyte* output the ubyte array to hold the random output. size_t length the length of the ubyte array output.
Randomize a ubyte array.
abstract SecureVector!ubyte randomVec(size_t bytes);
- Parameters
size_t bytes number of bytes in the result - Returns
- randomized vector of length bytes
Return a random vector
final ubyte nextByte();
- Returns
- random ubyte
Return a random ubyte
abstract const bool isSeeded();
- Returns
- true if this RNG was already seeded, false otherwise.
Check whether this RNG is seeded.
abstract void clear();
Clear all internally held values of this RNG.
abstract const @property string name();
Return the name of this object
abstract void reseed(size_t bits_to_collect);
- Parameters
size_t bits_to_collect is the number of bits of entropy to attempt to gather from the entropy sources
Seed this RNG using the entropy sources it contains.
abstract void addEntropy(const(ubyte)* input, size_t length);
- Parameters
const(ubyte)* input a ubyte array containg the entropy to be added size_t length the length of the ubyte array in
Add entropy to this RNG.
abstract class NullRNG: botan.rng.rng.RandomNumberGenerator;
Null/stub RNG - fails if you try to use it for anything
class SerializedRNG: botan.rng.rng.RandomNumberGenerator;
Wraps access to a RNG in a mutex
