Thanks for the proof of concept! I guess it ended up okay. But can
The RFC5869 compliant Key Derivation Function is implemented as a
random number generator considering that it behaves like a deterministic
RNG.
The extract and expand phases use different instances of the underlying
keyed message digest cipher to ensure that while the extraction phase
generates a
