This option signifies that the kernel's random number APIs are

|
permitted to return values that are not truly random.
|
|
This capability is provided for testing purposes, when a truly random
|
|
number generator is not available. The non-random number generator
|
|
should not be used in a production environment.

Enables the Xoroshiro128+ pseudo-random number generator, that

It is so named because it uses 128 bits of state.
