Question

A function converts data into a string of characters and the string of characters cannot be revers to re-create the original data. What type of function is this?

Answer 1

A function that converts data into a string of characters that cannot be reversed to recreate the original data is called a one-way hash function.

Step-by-step explanation:

This function is an example of a one-way hash function.

A one-way hash function is a mathematical function that takes an input (in this case, the data) and produces a fixed-size string of characters, known as a hash. The key characteristic of a one-way hash function is that it is not possible to reverse the process and obtain the original input from the hash.

One example of a commonly used one-way hash function is the SHA-256 algorithm, which is used to secure passwords and verify the integrity of data.
