class Random
Defined at line 17 of file ../../third_party/cobalt/src/lib/crypto_util/random.h
An instance of Random provides some utility functions for retrieving
randomness.
Public Methods
void RandomBytes (byte * buf, std::size_t num)
Writes |num| bytes of random data from a uniform distribution to buf.
The caller must ensure that |buf| has enough space.
void RandomString (std::string * buf)
Writes |buf->size()| bytes of random data from a uniform distribution
into buf.
uint32_t RandomUint32 ()
Returns a uniformly random integer in the range [0, 2^32-1].
uint64_t RandomUint64 ()
Returns a uniformly random integer in the range [0, 2^64-1].
bool RandomBits (float p, byte * buffer, std::size_t size)
Writes 8 * |size| independent random bits to |buffer|. For each bit the
probability of being equal to one is the given p. p must be in the range
[0.0, 1.0] or the result is undefined. p will be rounded to the nearest
value of the form n/(2^32) where n is an integer in the range [0, 2^32].
|size| must be less than or equal to 256.
Returns false to indicate failure.
