Describe the properties of hashes that make them ideal for identifying a particular digital item.

What will be an ideal response?


Hashes are mathematical functions that have the following properties that make them ideal for this purpose:
·      Regardless of the size of their input, hash functions produce a fixed size output (128 bits for MD5 and 160 bits for SHA-1).
·      It is computationally infeasible to determine a particular hash value based on a given input.
·      It is computationally infeasible to find another input that could produce the same output value as a given input.
