Function Documentation
| void randpool_add | ( | EntropyPool * | pool, |
| void * | data, | ||
| size_t | entropy | ||
| ) |
Add.
- Parameters:
-
entropy bits from data buffer to the entropy pool
Definition at line 120 of file randpool.c.
| void randpool_get | ( | EntropyPool * | pool, |
| void * | _data, | ||
| size_t | n_byte | ||
| ) |
Get.
- Parameters:
-
n_byte from entropy pool. If n_byte is larger than number byte of entropy in entropy pool, randpool_get continue to generate pseudocasual value from previous state of pool. n_byte number fo bytes to read. pool is the pool entropy context. _data is the pointer to write the random data to.
Definition at line 205 of file randpool.c.
| void randpool_init | ( | EntropyPool * | pool, |
| void * | _data, | ||
| size_t | len | ||
| ) |
Randpool function initialization.
The entropy pool can be initialize also with a previous entropy pool.
