Detailed Description
Random number generator interface.
This abstract class is used to hold a RNG object It provides explicit functions to generate:
- random key for Double Ratchet
- random keys Id on 31 bits. It also expose a generic function to generate random in a buffer

pure virtual |
fill the given RandomSeed buffer with Random bytes
- Parameters
-
[in,out] buffer point to the beginning of the buffer to be filled with random bytes
Implemented in lime::bctbx_RNG.
◆ randomize() [2/3]
|
pure virtual |
Generate a 32 bits unsigned integer(used to generate keys Id) The MSbit is forced to 0 to avoid dealing with DB misinterpreting unsigned values into signed one Our random number is actually on 31 bits.
- Returns
- a random 32 bits unsigned integer
Implemented in lime::bctbx_RNG.
◆ randomize() [3/3]
|
pure virtual |
fill a buffer with random numbers
- Parameters
-
[in,out] buffer The buffer to be filled with random (callers responsability to allocate memory) [in] size size in bytes of the random generated, buffer must be at least of this size
Implemented in lime::bctbx_RNG.
