Assume a good 128-bit cryptographic hash function. Assume there is a particular value, d, and you'd like to find a message whose message digest (i.e., hash value) is d. Given that there are many more 2000-bit messages that map to a particular 128-bit message digest than 1000-bit messages, would you theoretically have to test fewer 2000-bit messages to find one that has a message digest of d than if you were to test 1000-bit messages and why
