/*! \file isc/random.h
 * \brief Implements pseudo random number generators.
 *
 * Two pseudo-random number generators are implemented, in isc_random_*
 * and isc_rng_*. Neither one is very strong; they should not be used
 * in cryptography functions.
 *
 * isc_random_* is based on arc4random if it is available on the system.
 * Otherwise it is based on the posix srand() and rand() functions.
 * It is useful for jittering values a bit here and there, such as
 * timeouts, etc, but should not be relied upon to generate
 * unpredictable sequences (for example, when choosing transaction IDs).
  *
 * isc_rng_* is based on ChaCha20, and is seeded and stirred from the
 * system entropy source. It is stronger than isc_random_* and can
 * be used for generating unpredictable sequences. It is still not as
 * good as using system entropy directly (see entropy.h) and should not
 * be used for cryptographic functions such as key generation.
