- * Maximum allocation size for RANDOM_POOL buffers
- *
- * The max_len value for the buffer provided to the rand_drbg_get_entropy()
- * callback is currently 2^31 bytes (2 gigabytes), if a derivation function
- * is used. Since this is much too large to be allocated, the ossl_rand_pool_new()
- * function chooses more modest values as default pool length, bounded
- * by RAND_POOL_MIN_LENGTH and RAND_POOL_MAX_LENGTH
- *
- * The choice of the RAND_POOL_FACTOR is large enough such that the
- * RAND_POOL can store a random input which has a lousy entropy rate of
- * 8/256 (= 0.03125) bits per byte. This input will be sent through the
- * derivation function which 'compresses' the low quality input into a
- * high quality output.
- *
- * The factor 1.5 below is the pessimistic estimate for the extra amount
- * of entropy required when no get_nonce() callback is defined.

- * Initial allocation minimum.
- *
- * There is a distinction between the secure and normal allocation minimums.
- * Ideally, the secure allocation size should be a power of two.  The normal
- * allocation size doesn't have any such restriction.
- *
- * The secure value is based on 128 bits of secure material, which is 16 bytes.
- * Typically, the DRBGs will set a minimum larger than this so optimal
- * allocation ought to take place (for full quality seed material).
- *
- * The normal value has been chosen by noticing that the rand_drbg_get_nonce
- * function is usually the largest of the built in allocation (twenty four
- * bytes and then appending another sixteen bytes).  This means the buffer ends
- * with 40 bytes.  The value of forty eight is comfortably above this which
- * allows some slack in the platform specific values used.

- * The 'random pool' acts as a dumb container for collecting random
- * input from various entropy sources. It is the callers duty to 1) initialize
- * the random pool, 2) pass it to the polling callbacks, 3) seed the RNG, and
- * 4) cleanup the random pool again.
- *
- * The random pool contains no locking mechanism because its scope and
- * lifetime is intended to be restricted to a single stack frame.
