A good cryptographic hashing algorithm should produce random outputs; that is, the probability of any given hash value should be approximately the same as any other for randomly chosen input data. What would be the consequence of using a hash algorithm whose outputs were not random? Consider, for example, the case where some hash values are twice as likely to occur as others.
