TNL::Random Namespace Reference
Detailed Description
The
Random namespace is an interface to a cryptographically secure pseudo random number generator (PRNG).
Internally the Random namespace uses the Yarrow PRNG algorithm.

Functions |
void | addEntropy (const U8 *randomData, U32 dataLen) |
| Adds random "seed" data to the random number generator.
|
void | read (U8 *outBuffer, U32 randomLen) |
| Reads random byte data from the random number generator.
|
U32 | readI () |
| Reads a 0...U32_MAX random number from the random number generator.
|
U32 | readI (U32 rangeStart, U32 rangeEnd) |
| Reads a random number between rangeStart and rangeEnd inclusive from the random number generator.
|
F32 | readF () |
| Reads a floating point value from 0 to 1 from the random number generator.
|
bool | readB () |
| Returns a single random bit.
|
void * | getState () |
| Returns an opaque pointer to the random number generator's internal state for use in certain encryption functions.
