| * 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. |
