* 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

* 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

*
* Porting guide.
*
* Obligatory macros:
*
* DATA_ORDER_IS_BIG_ENDIAN or DATA_ORDER_IS_LITTLE_ENDIAN
* this macro defines byte order of input stream.
* HASH_CBLOCK

* HASH_LONG

* HASH_CTX
* context structure that at least contains following
* members:
* typedef struct {
* ...
* HASH_LONG Nl,Nh;
* either {
* HASH_LONG data[HASH_LBLOCK];
* unsigned char data[HASH_CBLOCK];
* };
* unsigned int num;
* ...
* } HASH_CTX;
* data[] vector is expected to be zeroed upon first call to
* HASH_UPDATE.
* HASH_UPDATE
* name of "Update" function, implemented here.
* HASH_TRANSFORM
* name of "Transform" function, implemented here.
* HASH_FINAL
* name of "Final" function, implemented here.
* HASH_BLOCK_DATA_ORDER
* name of "block" function capable of treating *unaligned* input
* message in original (data) byte order, implemented externally.
* HASH_MAKE_STRING
* macro converting context variables to an ASCII hash string.
