Question

Is the amount of change in the output hash is proportional to the change in the input data

Answer 1

Answer:

The data used in ups computer

Answer 2

Explanation:

The hash file is changed when the data is modified because the information within the file has changed and it is considered a new/different file.

 A hash function is a versatile one-way cryptographic algorithm that maps an input of any size to a unique output of a fixed length of bits. The resulting output, which is known as a hash digest, hash value, or hash code, is the resulting unique identifier we mentioned earlier.  

        Hashing uses functions or algorithms to map object data to a representative integer value. A hash can then be used to narrow down searches when locating these items on that object data map. For example, in hash tables, developers store data -- perhaps a customer record -- in the form of key and value pairs.

  Yes. The range of any hash function is limited by the number of bits. For example, if we were to use a hash function outputting 8 bits, then we only have 256 possible outputs; so if we have more than 256 possible inputs then we are guaranteed to have a collision.One of the core ideas of a hash function is that it provides the same output every time it is given a certain input. If you're trying to get a different hash value for the same input, using the same function, then you would need to add another layer of modification into the mix.
