+## Parameters

+| ---------- | --------- |
+| `dest`     | `void *`  |
+| `size`     | `size_t`  |

+| ------------------  | -------------------------------------------------------- |
+| **Return type**     | [`why2_bool`](../../../../types/core/flags/why2_bool) |
+| **Header comment**  | `WRITE CRYPTO-SECURE RANDOM NUMBER INTO dest`            |
+| **Added in commit** | [`f95608f52a0a82b3a8c005c7f8dad0b9cf93202a`](https://github.com/ENGO150/WHY2/commit/f95608f52a0a82b3a8c005c7f8dad0b9cf93202a) |
+
+## Description
+
+Function passes `dest` and `size` into [`RAND_bytes`](https://docs.openssl.org/1.1.1/man3/RAND_bytes) function and gets the output value. If output value is equal to `1`, returns `true`, otherwise `false`.
+
+`dest` is where the output value should be stored, `size` sets the allowed size to write. Should be `sizeof(dest_datatype)`.

+
+## Description
+
+Function inits pseudo random number generator `struct` with `seed`. Seeded numbers can be used with [`why2_seeded_random`](../why2_seeded_random). Also, there is no need to deallocate the PRNG.

+## Description
+
+Function generates pseudo random `int` with PRNG created in [`why2_seed_random`](../why2_seed_random). The function uses OpenSSL's [`HMAC`](https://docs.openssl.org/1.1.1/man3/HMAC).

 ## Description
 
-Function takes `input` parameter and divides it into segments of [`WHY2_SUM_SEGMENT_SIZE`](../../../../macros/core/crypto/why2_sum_segment_size.md). Each segment does some xoring, math using [`WHY2_SUM_BASE_PRIME`](../../../../macros/core/crypto/why2_sum_base_prime.md) and modulates each segment with [`WHY2_SUM_MOD_PRIME`](../../../../macros/core/crypto/why2_sum_mod_prime.md). The result is then added together and returned.

The result is then added together and returned.
 
 Output value grows rapidly with increasing `input` length, but unless you are using enormously large keys, nothing should overflow. Function was tested with lengths up to 4096 chars and output was only about 0,0000014 % of the `ULL` range.
