Furthermore given two different passphraes P1 and P2, a single known
constant C, H(C + P1) and H(C + P2), is finding a collision for either
made any easier than finding a collision for H(P1) or H(P2) if an
attacker knows these instead?
My guess would be that if Length(C + P1) > Length(H(C + P1)) but
Length(P1) <= Length(H(P1)) then the task would be made easier. But to
be honest it's all a bit much for me to visualise.
