MASTG-KNOW-0070: Random Number Generator

Apple provides a Randomization Services API, which generates cryptographically secure random numbers.

The Randomization Services API uses the SecRandomCopyBytes function to generate numbers. This is a wrapper function for the /dev/random device file, which provides cryptographically secure pseudorandom values from 0 to 255. Make sure that all random numbers are generated with this API. There is no reason for developers to use a different one.
