comment What is degree of randomness in individual bits of MD5 hash?
Yes... there's a whole list of them above. Uniformity over the set of possible outputs is a characteristic of hash functions in general. If that's not convincing enough, then you can always write a script that hashes a bunch of random data and check for yourself.

comment What is degree of randomness in individual bits of MD5 hash?
Yes, that's correct. Given random inputs, the output of MD5 is statistically uniformly random. MD5 is "broken" not because the distribution of its outputs is skewed, but because careful cryptanalysis showed that it's possible to create inputs that yield specific outputs. However, these "special" inputs are few and far between when compared to the space of all possible inputs, so they don't really affect the statistical properties of MD5's output.

comment What is degree of randomness in individual bits of MD5 hash?
Yes, that's right - a bit is binary by definition. MD5 takes an input of arbitrary length - any number of bits - and produces 128 bits of output. Typically this output is displayed as a string of 32 hex digits.

comment Alice and Bob's crush
This idea depends on Alice and Bob using a scale with more than two values to "rate their affection" for one another. In this case, they only learn if their selected values are equal.
