The three functions has been modeled after the arc4random family of functions, and they will always return random bytes. The isc_random family of functions internally use these CSPRNG (if available): 1. getrandom() libc call (might be available on Linux and Solaris) 2. SYS_getrandom syscall (might be available on Linux, detected at runtime) 3. arc4random(), arc4random_buf() and arc4random_uniform() (available on BSDs and Mac OS X) 4. crypto library function: 4a. RAND_bytes in case OpenSSL 4b. pkcs_C_GenerateRandom() in case PKCS#11 library
