SecureRandom with NativePRNG vs SHA1PRNG

Question

I need to generate cryptographically strong random numbers and byte arrays. For this purpose, I\'m using Java\'s SecureRandom class. But I\'m not sure to choose

Answer 1

As from a ref. here:

Native PRNG implementation for Solaris/Linux. It interacts with /dev/random and /dev/urandom, so it is only available if those files are present. Otherwise, SHA1PRNG is used instead of this class.

The SUN provider might be used as default (mainly dependent on the order of the provider which is present).
