One more question: is it not possible to mix in data into the DRNG? I thought
it would be possible with the Qualcomm DRBG.
Note, I am asking because of my /dev/random drop-in-replacement
implementation, any RNG from the kernel crypto API can be configured to be
used as an output DRNG. Though, this will only work if the DRNG also accepts
seed from the software noise sources.
Ciao
Stephan
