SecurityPkg/RngDxe: add rng test
|
||
|
|
|
||
|
|
Check whenever RngLib actually returns random numbers, only return
|
||
|
|
a non-zero number of Algorithms if that is the case.
|
||
|
|
|
||
|
|
This has the effect that RndDxe loads and installs EFI_RNG_PROTOCOL
|
||
|
|
only in case it can actually deliver random numbers.

||
