comment Strange Password Hashing
Hi there. Crypto.SE discourages custom algorithm analysis, which is really the essence of this question. You may receive better information by sifting your question down to a set of specific questions about achieving certain cryptographic properties. As it stands, the question is possibly in danger of being removed.

comment Deterministically combine more than one source of entropy
I think the canonical way to combine two numbers uniformly distributed between 0 and n is to just add them mod n. (Eg, XOR is often used for doing so, and it is just bitwise addition mod 2.) In the case of floating point, however, it may introduce precision bias due to precision limitations.
