description:

|
Estimated number of bits of true entropy per 1024 bits read from the rng.
|
|
Defaults to zero which causes the kernel's default quality to be used
|
|
instead. Note that the default quality is usually zero which disables
|
|
using this rng to automatically fill the kernel's entropy pool.
