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.
