* The RNG function should fill 'size' random bytes into 'dest'. It should
|
|
* return 1 if 'dest' was filled with random data, or 0 if the random data could
|
|
* not be generated. The filled-in values should be either truly random, or from
|
|
* a cryptographically-secure PRNG.
|
|
*
|
|
* A cryptographically-secure PRNG function must be set (using uECC_set_rng())
|
|
* before calling uECC_make_key() or uECC_sign().
|
|
*
|
|
* Setting a cryptographically-secure PRNG function improves the resistance to
|
|
* side-channel attacks for uECC_shared_secret().
|
|
*
|
|
* A correct PRNG function is set by default (default_RNG_defined = 1) and works
|
|
* for some platforms, such as Unix and Linux. For other platforms, you may need
|
|
* to provide another PRNG function.
